Purchased because it is Simon type and cheap. Making is solid, but it is hard in all, work such as bending and stretching or knee attachment, etc. I feel pain on the instep and I can not work. Although the shell is clearly described as natural leather, as long as you see the pain and peeling of the surface, it looks like synthetic leather and lacks durability. I will not buy it again. I will replace it with FD 11 of Simon which I used until now.
Although I bought it clearly, it did not become useless without trouble. Immediately after wearing, it was able to swell in the feet in about 20 minutes, the material was quite hard, fingertips fell and it was misery. I never buy it twice.
