Flux adapt waterproof runner

Flux adapt waterproof runner shoes in lunar grey Website says to size up a half size (i am normally 8.5 and ordered a 9) Wanted these for the wide toe box however they were tight around the top of my foot, my husband has the same shoes and didn’t have this problem. Wore them 1 time for a 12-5 shift, they are practically brand new! Unisex women’s 9, mens 7.5
