They are very good, value for money. I bought size 38 but when I tried them on, they didn't fit me because I have wide feet. I exchanged them for size 39. Now that I have worn them and they have stretched, maybe I should have kept size 38 because my foot slips forward. Ideally, maybe I would have taken size 38.5 if it existed, as I mentioned before, I have wide feet. Other than that, the material is great, and this particular company (from what I researched a little) is also environmentally friendly! :)
