I used it for the first time couple days ago, and it worked as expected. But for its purpose? They well exceeded my expectations. Purchased another pair just to make sure I will have them for years and years to come. Because they?re white, they did get dirty very quickly, but I?m not too bothered about that and I was able to wipe most of the dirt off with a damp cloth. Solid construction, fairly sturdy. the 8th screw was nearly impossible to get out. Since I got these shoes theyve pretty much always been on my feet. I tried it once for running and its horrible feeling. It really ruined the inner tracks of records for me. I just received my waist trainer and put it on.
