Well Dave you caught me out, I didn't enter their site because with dial-up those flash pages take ages to load. Now I see that they are also making models with straps but when I got mine there was only one style and it was strapless. I guess they are trying to compete with the competition. If you are contemplating getting some I recommend them highly, not only are they very comfortable but, for me, they have proven to be therapeutic for plantar fasciitis. They stay on quite nicely without straps.
