well I have be wear these for a week and I have scab on both foot between my big toe and the piggy next to it . I be in a bit of pain as we speak . I understand that break in time be necessary but this seem a bit extreme . they do smell pretty awful for the first week as the other poster note , like hot glue . the material stain pretty easily which be a problem if you toe be bleed -lrb- do not take these out for a long walk if you have not break they in yet -rrb- . on the other hand , they seem well build and have arch support . I be also about a half inch taller in these than my other flop which be not so bad . they also look nice and have a solid flip-flop noise , sound like the door of a Aston Martin close with every step . I would love these if it be not for the pain , though maybe my foot have just be make soft by this desk job . edit - after about two week they no longer hurt to wear . I plan on wear these for at least the next summer . just get a size bigger than you think you need , these be snug fitting flippy floppy .
