because I have be rob and assault . First off , the quality be terrible . like other , the nub start pop off nearly from day one . I own a lot of adida product and this be by far the worst I have ever purchase . thanks for steal my money . second , my foot have never feel worse . the sole of my foot feel like they have be stab to death to the point that I have to ice my foot to feel better . I buy these in hope of `` massage '' my foot after run , as I be lead to believe by the product name . instead ... ouch . I would like to note that I be a average size guy . no one -lrb- well , in America at least -rrb- would refer to I as fat or obese . my doctor whine at I to drop some weight , but I be not heavy enough for these sandal to be fall apart and cause severe pain . I should have go with the callissage as I have those before , however I find the `` massage '' effect of those to be nonexistent .
