Sounds not amazing but it is pretty cool. The webbing where you place your shoes in not very deep, its about 8". Ich würde es noch mal kaufen. Dadurch, dass wir oft sehr eng stellen müssen, ist da nicht viel zum Dranheften. On the first wear the toe part split away from the sole. WOULD DEFINITELY RECOMMEND. One thing I love is that if I do walk around all day in these, I dont have to worry about my foot cramping or feeling soreness, especially in my arch. Due to my own improvements and improvising, I was able to make it work but it was extremely frustrating. I am disappointed in this product - I ordered 2 sets originally, and then realized I could use a little more covered ground space. But it could clearly be a plus to put a better description as well as the Birkenstock size chart in image.
