I have problem feet , and have had 3 surgeries and a fusion on my left foot .Mbt were recomended but they are not comfortable as I have a total knee  replacment .I can get around very well in the FITFLOPS I can not wear the thongs at all, but the sandals would be wonderful if the ball of the foot adjusted more so I give them a  3 out of 5 , and the sneekers are not as good as the sole is not like the boots. The boots are really good and if you have had hallux problems or a weil osteotomy give them a try!!!!I give them a 4 out of 5 as they are hot in warmer weather even the short boots, love them and the tall boots  great fit most of the time .I wear a 10 in the shoes and boots and a 9 in the sandals , hope this is of help.
