My husband has been having foot issues from wearing his work shoes for 16+ hours everyday.  I have reef flip-flops and always loved them so i decided to get him a pair to put on while he is putting around the house when he gets home from work and he loves them and his feet don't bother him like they used to  he wore them all around SeaWorld and his feet never bothered him.  I bought the pair with the bottle opener for giggles and it's pretty funny when some unsuspecting person sees him open my beer with his shoe.  i would definitely reccommend reef sandals (with or without the bottle opener) to anyone that wants a comfy pair of flip flops.
