For the price these are awesome, REI would have sent us to the savings account. Typical Teva quality, which in my opinion is excellent. I think that this could resolve if I reposition my foot from time to time whenever they shift as the leather is breaking in. Some fraying of yarn has happened where its sewn to the sole. Would be nice to if they had 1/2 sizes. Fits perfectly around the case and has the opening to charge your headphones without having to take them out. I know that only the microwobble styles are the ones that are going to work BUT its not all of them. Normally I don?t give 5 stars, BUT I am this time. Perfect fit for my sons USB headphones. The edges of the pads are more square than the originals.
