These are the most comfortable shoes ive ever worn. I have lower back issues.. and these just seem to help. I bought them for walking in vegas... i survived. No blisters.. in fact... my feet didn't even hurt. We measured and walked about 10 miles each of the 3 days we were in vegas. Get these shoes! Youre welcome. Ps.. get a half size bigger or a full size if u have a wide foot.
