I normally wear a size 8 & 1/2 wide, but ordered up a half size. I wanted the extra room for walking down steep hills - I didn't want my toes hitting the end of the shoe. I also wanted room for my plantar fasciitis inserts and bands. Im still limping around but I feel that these shoes are giving me the support I need to heal. They do seem a little loose in the heel, but hard to tell with the limping I am doing. Im not having any discomfort from the heel feeling loose. Overall I give these shoes a 5 star for comfort and value. They fit my wide feet perfectly.
