ASICS Gel-Kayano 31 Review: A$259.99

Introduction

If you've been running in stability shoes for any length of time, you'll know the compromise that usually comes with the territory: support, yes, but often at the cost of a ride that feels wooden underfoot, an upper that traps heat, and a silhouette that looks like it belongs in a rehabilitation clinic rather than on a Sunday morning loop around the tan or the Bay Run. The ASICS Gel-Kayano has spent over three decades navigating that tension, and the 31st iteration makes a convincing case that the tension is finally resolving in the right direction.

The Gel-Kayano 31 is a premium daily trainer built specifically for overpronating runners — those whose feet roll inward on footstrike, increasing load on the ankle, knee, and hip over time. It's not a shoe for everyone, and ASICS doesn't pretend otherwise. What makes it worth scrutinising at this price point is whether the cushioning and stability technology has genuinely evolved, or whether you're paying for brand heritage and a fresh colourway. After examining the construction in detail and weighing it against the consistent pattern of Australian buyer feedback, the answer is more encouraging than previous Kayano generations.

For Australian runners heading into spring training — whether that's building a base for a summer fun run, returning to the paths after a cooler July and August, or simply replacing a worn-out pair — the Gel-Kayano 31 arrives with real credentials. The question is whether those credentials justify A$259.99.

Price

A$259.99 — available at The Iconic, David Jones, Rebel Sport, Myer, ASICS Australia website, and Amazon Australia.

That price sits at the upper end of the performance running shoe bracket in Australia. For context: Brooks Ghost 16 retails around A$219.99, and the New Balance Fresh Foam X 860v14 lands at approximately A$229.99. You're paying a premium for the Kayano's specific combination of stability engineering and cushioning volume, and that premium is not purely cosmetic.

The A$259.99 price point will give pause to runners who treat their trainers as purely functional kit. It shouldn't deter you if you have confirmed overpronation, have been through a gait analysis, or are already in the Kayano lineage and upgrading from a previous version — the technology improvements in the 31 are tangible enough to warrant the outlay. If you're a neutral runner who simply wants a cushioned daily trainer, you're paying for stability infrastructure you don't need, and you'd be better served by the ASICS Gel-Nimbus 26 or a comparable neutral option.

The Iconic occasionally runs promotional codes and frequently offers free returns, which is a meaningful practical advantage when buying running shoes online without the ability to trial them on your specific surface first.

Materials and Construction

The Gel-Kayano 31 is built around three technology layers that each address a distinct problem, and understanding what they actually do helps you assess whether this shoe is the right investment.

FF BLAST PLUS ECO midsole: This is the primary cushioning compound, and it's a meaningful upgrade on the foam used in earlier Kayano generations. It's softer and more responsive than the previous FF BLAST formulation, which addressed a persistent criticism that the Kayano rode too firm for the cushioning category it occupies. The ECO designation reflects the inclusion of recycled content in the compound — ASICS hasn't disclosed the precise percentage publicly, but the sustainability positioning is consistent with broader moves across the brand's product range. For Australian runners who factor environmental credentials into purchasing decisions, it's a genuine point of difference, not a marketing label.

LITETRUSS medial post: This is the stability mechanism — the component that corrects overpronation by reinforcing the medial (inner) side of the midsole to resist inward roll. Where older support shoe designs used a hard, dense foam wedge that created a noticeable two-density feel underfoot, LITETRUSS is designed to integrate more seamlessly into the overall ride. The result is stability that functions as a corrective guide rail rather than a blunt stop. Some experienced overpronators with more severe mechanics will find this less aggressive than they're used to — that's addressed in the Cons section — but for the majority of mild-to-moderate overpronators, the transition in feel is a positive development.

3D Space Construction: Structural patterning within the midsole creates zones that compress and rebound at different rates depending on where and how your foot strikes. In practice, this means the heel cushioning and forefoot cushioning behave somewhat independently, accommodating the different load demands of heel-strikers versus midfoot-strikers. It's a more nuanced midsole architecture than a single-compound foam block.

Engineered knit upper: The upper is a woven knit construction that replaces the traditional engineered mesh seen in Kayano versions up to the late 20s range. It conforms closely to the foot without requiring the stiff overlays that older versions relied on for structure. The breathability improvement over previous Kayano mesh uppers is consistently noted by Australian buyers, and it's particularly relevant for spring running in Sydney, Melbourne, and Brisbane — where September and October temperatures can fluctuate between 12°C mornings and 25°C afternoons within the same week. The trade-off is water resistance: the knit construction absorbs moisture more readily than a tight mesh in wet conditions, which is a genuine limitation on dewy morning runs or light spring rain.

AHAR+ carbon rubber outsole: AHAR+ (ASICS High Abrasion Rubber Plus) is placed at high-wear zones under the heel and forefoot. It's a proven compound that holds up well on the bitumen and concrete surfaces that characterise Australian running paths in coastal cities. Multiple Australian buyers who've logged 600–800 km in the Kayano 31 report that the outsole shows minimal degradation, which is a credible indicator of durability at this price point.

Comfort

The most significant change in the Gel-Kayano 31 relative to its predecessors is the feel underfoot on the first wear. Earlier iterations of the Kayano were known for a break-in period that could run to 50–80 km before the shoe reached its optimal comfort level. The 31, by contrast, delivers a noticeably accommodating ride from the first run, and Australian reviewers consistently describe it as the most comfortable Kayano in recent memory.

The FF BLAST PLUS ECO foam is responsible for most of that improvement. It has a plush, slightly springy character that sits between the firmer, more performance-oriented feel of the ASICS Nimbus and the very soft, marshmallow-like response of something like the Hoka Clifton. For daily training distances — 6 to 16 km — it provides sustained cushioning without the energy return starting to feel unpredictable or the foam packing out noticeably before you've finished the session.

The knit upper contributes meaningfully to the comfort picture during Australian spring conditions. It moves with the foot naturally, doesn't create hot spots on longer runs, and allows enough airflow to prevent the heat build-up that heavier mesh or synthetic overlays trap against the foot. If you've previously avoided the Kayano because of its reputation for feeling bulky, the 31 is worth revisiting: it's a lighter, more agile experience than the version number suggests.

One comfort caveat worth flagging: a small but consistent proportion of Australian buyers report mild heel slippage in the first few weeks of wear. This typically resolves as the heel counter beds in and the knit upper conforms to foot shape, but if you're sensitive to heel movement or prone to blisters in that area, lacing the shoe with a heel-lock technique from the outset will address it before it becomes an issue.

Fit and Sizing

The Gel-Kayano 31 fits true to size by the strong consensus of Australian buyers. If you're already in the Kayano lineage, there's no version-to-version sizing change to account for. If you're buying ASICS for the first time, the AU sizing scale is consistent with US sizing and runs true for the majority of foot shapes.

The standard women's fit is a D width, which ASICS characterises as a medium width. Australian feedback suggests this accommodates average foot widths comfortably, but buyers with broader forefeet — particularly across the metatarsal heads — may find the fit snug through the front third of the shoe. If you're in any doubt, trying in-store at Rebel Sport or a specialist running retailer before purchasing online will save you the returns process. A men's 2E wide fit is available, which is a meaningful option given that wider male foot shapes are common among Australian recreational runners.

Available in Women's AU 5–12 and Men's AU 6–15, the size range covers the majority of Australian buyers. The Iconic carries the full size spread and has reliable stock depth across the popular mid-range sizes (Women's 7–10, Men's 8–12), making it the most practical online option for standard sizing. For less common sizes at either end of the range, checking ASICS Australia's own website or Rebel Sport's stock is worth the extra step.

One practical note for buyers transitioning from older-generation Kayanos: the knit upper has slightly less volume in the toe box than the older mesh versions due to the more form-fitting construction. If you previously sized up half a size in the Kayano for extra toe room, verify whether that's still necessary before ordering.

How to Style It

The Gel-Kayano 31 is, unambiguously, a performance running shoe. Its design language reflects that — the profile is purposeful rather than lifestyle-casual, and the colourways on offer for spring 2025 are appropriately directional without crossing into fashion-trainer territory. Styling it requires working with that performance identity rather than against it.

1. The morning-to-market run kit
Pair the Lilac Hint/Violet colourway with a mid-rise, high-waisted running tight in charcoal or slate grey — Lululemon's Fast and Free tights or the Jaggad Interval Tight work well — and a relaxed-fit performance tank or breathable long-sleeve base layer in off-white or light grey. Post-run, throw a cotton-blend oversized bomber or track jacket over the top, and the combination moves from the running path to a farmers' market or café stop without looking like you've forgotten to change. The lilac in the shoe is soft enough to read as considered rather than loud.

2. The spring training set
The Pale Iris/Soft Sky colourway pairs cleanly with a colour-coordinated set in tonal blues or lavender — think a cropped zip-through training jacket over a fitted sports bra and matching mid-length bike shorts. Brands stocking this aesthetic in Australia include Lorna Jane, PE Nation, and ADANOLA (available via The Iconic). The result is a coherent head-to-toe training look that works for a session at an outdoor gym, a coastal path run, or a reformer Pilates warm-up. The shoe's clean lines don't compete with the set; they anchor it.

3. The athleisure commute
If your morning involves a run followed by a day that doesn't allow a full change, the Gel-Kayano 31's knit upper and lower-profile aesthetic than earlier Kayanos allows it to integrate into a casual office-adjacent outfit more convincingly than its predecessors. Try slim-cut chino-style pants in camel or olive (Uniqlo's slim ankle chinos are widely available in Australia and sit at the right hem length), a clean white relaxed-fit tee or lightweight cotton-blend long-sleeve, and the Midnight/Black colourway for a neutral-reads-as-deliberate finish. It's not a fashion sneaker, and it shouldn't pretend to be — but the overall effect is intentional rather than apologetic.

Alternatives

If the Gel-Kayano 31 doesn't align with your mechanics, budget, or preferences, these three stability or cushioned daily trainers are all available through major Australian retailers.

Brooks Adrenaline GTS 23 — approx. A$229.99
Available at The Iconic, Rebel Sport, and Running Warehouse Australia. The Adrenaline GTS 23 uses Brooks' GuideRails support system, which operates on a different philosophy to the Kayano's medial post: rather than reinforcing the medial side alone, GuideRails limits excessive movement on both sides of the heel, which some overpronators find produces a more natural corrective feel. The ride is slightly firmer than the Kayano 31 and the upper less breathable, but the A$30 price saving is meaningful if you're not committed to the ASICS platform. A reliable, honest stability shoe.

New Balance Fresh Foam X 860v14 — approx. A$229.99
Available at The Iconic, David Jones, and New Balance Australia. The 860v14 is a structured daily trainer that bridges the gap between motion control and cushioned neutral running. The Fresh Foam X midsole is softer than expected for a stability shoe, and the upper is well-ventilated for Australian spring and summer running. It runs slightly narrow in the toe box, so wider-footed runners should size up or try the wide fit variant. A strong alternative for overpronators who want more cushion than the Adrenaline GTS offers but feel the Kayano's price is difficult to justify.

Saucony Guide 17 — approx. A$219.99
Available at Running Warehouse Australia, The Iconic, and Saucony AU. The Guide 17 is Saucony's mid-stack stability offering, positioned below the Tempus in terms of cushioning volume. It uses a PWRRUN midsole with a TPU guidance frame for stability — a denser medial post than the Kayano's LITETRUSS, which makes it a better fit for severe overpronators who find the Kayano 31's stability insufficient. Lighter than the Kayano and priced A$40 less, it's the pick for runners who prioritise a more locked-down, corrective feel over plush cushioning.
