Nike Air International Triax £74.99

A new, better-fitting seamless upper for this firm, durably-cushioned staple of the big-guy and big-girl market. It’s not for runners with stability problems, but the polyurethane midsole and Max Air rear- and forefoot cushioning is designed for heavy impacts. The 384g International Triax is the men’s version; the Converge Triax is designed separately for women, on a wider-forefooted last than previous Nikes.
