These are beautiful, but the material of the straps is very stiff and unyielding. I get blisters on my toes each time I try to wear them. The height and incline are fine, but I wish I could soften up the straps without ruining them. If i had tried them on in store first, I would not have purchased them. I want to make them work and hate returning things, but the strap over the toes is maybe a centimeter too far forward if that makes sense. Rubs my toe knuckles in just the wrong place. I don't have particularly difficult feet to fit; these were just a mistake.
