I had decided on deerskin moccasins for my husband sinceI wanted him to have the most comfortable moccasin available. Well, these Moosehide mocs are everything and more! He wears a size 10 to 10.5 shoe, I ordered size 10 and the fit is perfect, with or without socks - I don't see that they run small as other reviewers have reported. I treated the leather with mink oil before he started wearing and I'm certain his intention is to wear them inside and out; of course, you wouldn't want to wear them while doing 'dirty' work outdoors but the rubber sole is plenty study to stand up to the mountain terrain outside our front door. My husband loves them and I couldn't be happier :)
