Length: True to size, though narrow feet may prefer a half size down
Width and toebox: A wider, more spacious forefoot than the Cloudmonster 3. Standard width only.
Fit notes: A high-volume upper, wide through the instep and midfoot, that needs the laces cranked down firmly to stop heel slip, and the thin gusseted tongue can cause lace pressure on the instep. Sizing is genuinely contested, with some sources recommending a half size down for average-width feet because the forefoot swims.
