Sizing
Length: True to size
Width and toebox: Medium, standard width with no radical tapering or toe cramping, and slightly more forefoot room than earlier Cloudflows. Standard width only.
Fit notes: No heel slippage with either light or midweight socks, and a midfoot hold reviewers described as a perfect wrap. The heel counter is notably flexible rather than stiff, and the forefoot is slightly snug with a light taper by design. No hot spots and no break-in needed.
