These are hands down the lightest most comfortable pull on boot I have ever put on my feet and I've wore them all! No break in period they are soft right out the box and they do run a full size bigger than normal. I wear a 10 ordered a 9.5 but could use a 9 because these are a little big without insoles. I own a fab shop so on my feet all day long for long hours on concrete. If you want a great boot buy these boots!
