Toe shape and width
A “wide” label does not tell you where the shoe is wide or whether the heel and instep will hold your foot.
Lems
Lems labels individual shoes Wide or Widest. Primal 3 and Primal Zen use its widest Natural-Shape last; Boulder Boot Grip Waterproof uses the narrower Wide last.
Xero Shoes
Xero describes its men’s range as wider than conventional shoes, but sizing and fit advice are model-specific. Do not transfer a Prio Neo fit assumption to a boot or sandal.
Bottom line: For maximum forefoot room, begin with a named Lems Widest model; otherwise compare the exact size chart and shape.
