New Balance has officially launched the Fresh Foam X 860v15 this week, the latest iteration of one of the running industry's most enduring stability platforms. After a soft release in late March, the shoe is now broadly available at a retail price of $150 (approximately £120), and early impressions suggest it represents a meaningful step forward from its predecessor. The headline change is a substantial increase in stack height — up from 38mm heel/30mm forefoot in the v14 to 43mm/35mm in the v15 — placing it squarely in the maximally cushioned stability category that has grown significantly in popularity since 2024.
The additional foam is Fresh Foam X, New Balance's flagship compound, which delivers a soft underfoot feel without the marshmallow-like instability that plagued some early high-stack designs. What keeps the 860v15 grounded — both literally and in terms of running feel — is the Stability Plane technology embedded within the midsole geometry. Rather than relying solely on a medial post, the Stability Plane creates a broader, more distributed platform that guides pronating feet through the gait cycle without the abrupt correction that traditional dual-density foams can produce. The result is support that feels less imposed and more intuitive, particularly on longer runs when fatigue begins to affect form.
On foot, the 860v15 excels in the role it is designed for: easy-paced daily training runs and long recovery miles. The increased stack translates into noticeably better protection on hard pavements, and runners dealing with conditions such as plantar fasciitis or posterior tibial tendon issues may find it a particularly effective choice. The trade-off, as with most high-stack stability shoes, is weight — the men's version tips the scales at around 310 grams in a UK size 9, which is appreciable on faster efforts. This is not a shoe built for tempo work or racing; it is built for the steady accumulation of training miles.
One of the 860's long-standing competitive advantages is its width range, and the v15 maintains that tradition. New Balance offers the shoe in Narrow (2A), Standard (D), Wide (2E), and Extra Wide (4E) lasts — a breadth of fit options that no other major brand currently matches in the stability category. For runners with wider feet who have historically struggled to find a well-fitting stability shoe, this alone makes the 860v15 worth serious consideration. The upper is constructed from an engineered mesh that accommodates foot swell on longer efforts without feeling loose at the midfoot during normal running.
The 860 line has been a fixture in New Balance's performance catalogue for nearly two decades, and the v15 feels like a confident, well-considered update rather than a reactive one. The brand appears to have resisted the temptation to over-engineer the platform, instead focusing on the two areas — cushioning volume and fit breadth — where runner feedback most consistently pointed. At £120, it sits at a competitive price point relative to comparable shoes from Brooks and ASICS. For runners who overpronate and prioritise long-run comfort over versatility, the 860v15 makes a strong case for itself as the default daily trainer of 2026.
