New Balance 860v15 vs ASICS Gel-Kayano 32 for Overpronation
Invisible stability versus adaptive precision. Two APMA-accepted approaches to correcting inward roll at different price points.
We don't just recommend shoes. We explain why they work for your feet.
What You Need to Know First
Overpronation occurs when the foot rolls inward excessively during the gait cycle, placing cumulative stress on the plantar fascia, posterior tibial tendon, medial knee, and hip. Stability shoes address this at the foot level by providing medial support that resists the inward roll before it travels up the kinetic chain. Two stability approaches dominate the current market. Geometry-based stability uses structural design, foam density gradients, and midsole architecture to guide the foot without the runner feeling an active correction. Adaptive foam-based stability uses a responsive material that changes its resistance based on the load applied, providing more correction when pronation is greater. The 860v15 leads with geometry-based invisible stability. The Kayano 32 leads with adaptive foam precision.
The New Balance Fresh Foam X 860v15 and ASICS GEL-Kayano 32 are two of the most podiatrist-recommended stability shoes for overpronation at different price points and with meaningfully different stability philosophies. Both are APMA accepted. Both correct overpronation effectively. But they approach the problem from opposite directions. The 860v15 uses New Balance's Stability Plane, a full-length medial wedge that works like a subtle tilt in the floor beneath your foot, raising the ground to meet your arch rather than forcing your foot into a corrected position. It is what the industry now calls invisible stability. The Kayano 32 uses ASICS' 4D Guidance System, an adaptive foam structure that responds to your specific gait pattern and actively resists inward rolling with precision tuned to your pronation severity. It is what podiatrists call mechanically precise stability. The 860v15 is the more affordable option at $145 to $155 versus the Kayano 32 at $160 to $170. The Kayano 32 is the more sophisticated clinical tool for serious runners with measurable overpronation.

Which One Is Right for You?
Both are excellent. Here is the honest case for each based on your specific situation.
New Balance Fresh Foam X 860v15
$145-$155
Choose this when
You want effective overpronation correction at a lower price point without the firmer, more structured feel of traditional stability shoes. The 860v15's Stability Plane acts like a subtle wedge that brings the ground up to meet the foot's natural position rather than forcing the foot into a corrected one, delivering invisible stability that feels more natural than traditional medial post designs. It is also the stronger choice for overpronators who also need wide width accommodation, as it comes in B, D, and 2E, and for runners who prefer a softer more cushioned ride alongside their stability correction. At $145 to $155 it is the more accessible option for patients managing overpronation on a budget without compromising clinical effectiveness.

Engineered mesh upper for breathability
Medial post controls overpronation
ASICS GEL-Kayano 32
$160-$170
Choose this when
Your overpronation is moderate to severe and you need the most mechanically precise stability system available in a daily trainer. Dr. Tom Biernacki, DPM, describes the Kayano 32's DuoMax as providing a firmer medial density that actively resists overpronation with every stride, calling it the most mechanically precise stability shoe he prescribes for serious runners with moderate to severe overpronation. The Kayano 32 is also the stronger choice for runners who want GEL cushioning in both the heel and forefoot alongside their stability correction, and for anyone who has tried geometry-based stability shoes without achieving adequate overpronation control. Its 4E extra wide width option also extends its clinical reach to patients with the widest feet.

The Honest Verdict
Both shoes are APMA accepted and clinically effective for overpronation. The 860v15 is the stronger choice for runners who want invisible geometry-based stability at a lower price point with a softer more cushioned feel. The Kayano 32 is the stronger choice for runners with moderate to severe overpronation who need adaptive precision stability and premium GEL cushioning. As Dr. Tom Biernacki notes, for budget-conscious patients the 860 delivers nearly equivalent stability performance at a meaningfully lower price. For serious runners whose overpronation has not responded to lighter stability systems, the Kayano 32 is the appropriate clinical escalation.
Answer These. Then Decide
Four quick questions that point you toward the right shoe for your specific situation.
Is your overpronation moderate to severe and have lighter stability systems not provided adequate control?
Is price a meaningful consideration and you want the most clinically effective option at a lower cost?
Do you want GEL cushioning in both heel and forefoot alongside your stability correction?
Do you prefer a softer more cushioned ride over a firmer more structured stability feel?
Do you need 4E extra wide width alongside overpronation correction?
Frequently Asked
Which is better for overpronation, New Balance 860v15 or ASICS Gel-Kayano 32?
Both are APMA accepted and clinically effective for overpronation. The 860v15 is better for mild to moderate overpronation where invisible geometry-based stability is sufficient, and for budget-conscious patients where Dr. Tom Biernacki DPM notes it delivers nearly equivalent stability performance at a lower price. The Kayano 32 is better for moderate to severe overpronation where adaptive precision stability is needed, and for runners who want GEL cushioning in both heel and forefoot alongside their correction. A podiatric gait assessment is the most reliable way to determine which level of stability your overpronation requires.
What is the difference between the New Balance 860v15 and ASICS Gel-Kayano 32?
The most clinically significant differences are stability approach, drop, and price. The 860v15 uses a Stability Plane full-length medial wedge with a 6mm drop and softer cushioning at $145 to $155. The Kayano 32 uses a 4D Guidance adaptive foam system with an 8mm drop and firmer GEL cushioning at $160 to $170. The 860v15 delivers invisible stability that feels more natural underfoot. The Kayano 32 delivers mechanically precise stability that actively resists inward rolling. The Kayano 32 also offers 4E extra wide width while the 860v15 caps at 2E.
Is the New Balance 860v15 good for flat feet?
Yes. The New Balance 860v15 carries the APMA Seal of Acceptance and is specifically designed for overpronation, the most common consequence of flat feet. Its Stability Plane full-length medial wedge provides geometry-based correction that resists arch collapse without the intrusive feel of traditional medial posts. It is most appropriate for flat-footed patients with mild to moderate overpronation who want effective stability correction at a lower price point. For severe flat feet with significant overpronation, the ASICS Gel-Kayano 32 or Brooks Adrenaline GTS 25 provide more aggressive correction.
Is the ASICS Gel-Kayano 32 worth the extra cost over the New Balance 860v15?
For mild to moderate overpronation, the 860v15 delivers nearly equivalent clinical results at a lower price and is the stronger value choice. For moderate to severe overpronation in serious runners, the Kayano 32's 4D Guidance adaptive precision and GEL cushioning in both heel and forefoot justify the additional cost. Dr. Tom Biernacki DPM specifically prescribes the Kayano 32 for serious runners with measurable rearfoot valgus who have tried other stability shoes without full success. If your overpronation falls into that category, the Kayano 32 is worth the premium.
