I didnt get the official non-slip mat which has terrible reviews. Vifa hat so viel Potenzial verschenkt. My little guys LOVES these shoes! Partamos de eso. I am writing this review before the Xbox Series X is out. Ive only worn them for a week around the house and there is already quite severe pilling of material where the ball of my foot rubs against the slipper. My only real complaint is that this thing takes a lot of fussing to be usable. What I like is that they have a little extra sole thickness than most and it has good texture on the sole, however the texture of the foot surface is very slick so my foot slides around. I had a hanger like this for shirts, and they just wouldnt sit right, so my expectations were very low when I purchased this one. When setup, the trainer is smooth with easy adjustment.
