Nice, comfortable fit made possible by straps that arent cosmetic additions but which can be fully adjusted to create a fit as tight or loose as you want. it play the noise. I have a feeling if it gets dropped it would break. I had a CNH removed from my ear a while back and certainly dont want to take any chances with getting another one. 4v for those timings to be stable, and Im fine with that. As well, unlike some other reviews, I found that the shoe was too loose/large (I went up half a size, but even so, it is due to the design), and find it often slipping off. Probably not an issue since the rubber grips the barbell and probably wont allow the weights to slide off as long as I keep the barbell parallel to the floor. They were always getting knocked around and made it impossible to vacuum. The footbed is so comfy and has so much support, that I do not want to take them off, when I wear them. Then you have the adjustable belt to put on and I actually had an hour glass figure!
