Let me give you a good visual as to the solid build and quality of these inversion boots. I am 6' 6" tall and weight 289 pounds and use these daily. I first put these on and had visions of me landing on my head so i had my hands down to absorb the fall but there was no fall. I would watch the rivets to see if they would bend at all or if the hooks would as well. They are solid sturdy construction. Hard plastic and steel. The padding is fine. I hear about the complaints from people saying it's not padded enough, the padding is fine.
