Foot width varies across every runner, and On offers wide sizing in select models like the Cloudrunner to account for this. Rather than assuming width needs follow gender lines, checking whether a preferred model offers a wide option — and trying it if the standard width feels tight across the forefoot — solves the problem more directly. A snug fit at the widest part of the foot can cause discomfort regardless of which size chart someone started from, so this is worth checking independently of any gender-based sizing assumption.
