They were very comfortable after the first few wearings. (took awhile for the straps to get stretched out enough for me)  I like the squishy softness under my feet. I wear them to work 4 of 5 days each week AND on weekends AND tend to wear them around the house more than any other flop I own. Which is maybe why they are beginning to stink. I've washed them off many times and sprayed them with Lysol, but that only helps for an hour or so. I'm going to try freezing them for 24 hours to kill the odor causing bacteria.. hopefully that will do the trick. I wish the surface had a non-porous coating like the cheap flip-flops from Old Navy or an anti-bacterial ingredient (like Crocs) to help prevent foot odor.
