these sandal be amazing if you give they the chance . many reviewer have say that they hurt and be uncomfortable . I would not say that they hurt but more towards the uncomfortable side if this be you first time wear they . however , after a couple day of wear they around the house , you foot should get use to they and the nub start to soften just a bit . now they be so comfortable to I that I try to find place to walk to in they ! I like the fact that the sandal strap be adjustable , but at the same time , very sturdy . in the summer I like to have the strap a little tighter . when it start get cold , I loosen the strap a bit so that I can wear sock with they around the house for my cold foot . one weird thing that I have discover be that , if I wake up and immediately put they on , they feel like they pinch the bottom of my foot just a bit . the feeling go away after a couple minute and I never have this feeling besides in the morning with these sandal . also , I would not wear these as shower sandal if I be you . the strap be line with feel on the inside and it soak up the water pretty well . in the summer it dry quickly but in the winter , the shoe might still be wet in the morning after shower at night . if you decide to shower with they , flush out the space between the nub once in a while with the shower head to get rid of trap sock lint or dust . another tip , if you do shower with they on , I suggest tip the shoe upside down afterwards to drain some water out because it will get trap between the nub . not a big deal but maybe this be what be cause people 's nub to fall off quickly ? I have have these sandal for 2 month now , and they look brand new despite the fact that I wear they everyday ! the size for the shoe seem small by half a size . I wear 10.5 's in Nike sneaker . however , I get the sandal in 11 's and they fit great ! the contour of the nub fit my foot exactly . these shoe be definitely a great investment . after wear they for so long , the sole do not seem to have worn too much . I much prefer to buy something nice that last a long time then to buy 5 pair of cheap flip flop that I have to constantly replace .
