Width and toebox: Medium. Volume was added across the Deviate line for v4 after earlier versions ran narrow, so the forefoot is spacious without being sloppy. Wide offered for men and women.
Fit notes: Ankle and heel lockdown are unusually secure for a plated shoe, and the gusseted tongue holds the midfoot without pressure. Runners with slightly narrow feet still get a good hold. No break-in reported.
