The antenna broke off. There was no sliding off the foot or loose straps, but it wasnt extremely comfortable to walk in due to the stiffness of the sole and strap placement. My daughter wears a size 11 in women. Working from home means these comfy slippers get worn much. Other than that, Im happy with the purchase and lets get the party started. Ill be honest when I say I was slightly worried about the quality of the earbuds for the price. I guess thats about it for my issues with the HT. For some reason, Life Stride put cushioning everywhere except under the ball of your feet, where your weight lands when wearing heels. I was a bit skeptical about this product given the affordable price. Both controllers are of excellent quality.
