I usually wear them until the sole wears down and then have them resoled once more before retiring them. These run very small. These are perfect and the material is high quality so we know they will last. Die Größe war gut, sogar etwas knapp. You can’t go wrong, they are great headphones. Wish I could have used them. A regular shoe would offer more support. The sandals do not look like they are orthotic, at all. I only plan on buying two more pair of heavier weights I’m and confident they’ll be able to fit comfortably as well. The seats were perfect.
