These shoes are created with a soft, pliable leather and come with a padded inner sole and an outer Rubber Sole.Don't worry about taking time to break them in! Our customers wear them right out of the box!Sizing: We have found sizing to be somewhat flexible with these amazing shoes! For the majority of customers, they find them to run very true to their normal shoe size.***If you wear a 1/2 size (ie 7.5), I recommend sizing up. This is a general recommendation.
