I bought these based on a friend's referral.  The sole is comfortable, but the straps are a little tight if you're like me and have chubbier feet.  If you do have chubbier feet you may want to order the wider strap version, to avoid the uncomfortable straps digging in.  I'm flat footed so I don't really notice arch support.  I bought this version instead of the wide strap variety because these were only $8.40 with prime shipping.
