Sizing
Length: True to size
Width and toebox: Forefoot runs normal to slightly wide. Standard and wide offered in men's and women's.
Fit notes: A wider midfoot with a comparatively low instep over the forefoot, and a stiff internal heel counter plus external rearfoot rails for hold. Some runners need to snug the laces to stop heel slip. The upper takes a run or two to settle.
