I have seen significant strength gains since using this. One super great runner or mountain trail hiker. It was amazing. Did have a slight dent but not enough for it to not work. So Ive had a pair of these controllers for a few weeks - putting them through the paces. I?m wearing them today without socks (still around the house because I don?t think they?re ready to wear to work or for a walk yet) and the forefoot and ankle straps have stretched and softened just as I hoped they would. Not impressed that I cannot return. These shoes are so cute but are different that the other Kaydee Flats I have purchased. First off, it arrived with a huge hole in it. SOUNDSTAGE : the least open of this group (not by much), though have immense detail and stereo width.
