These have a lump under the big toe in right shoe where the leather was folded under. I have another pair of Spira shoes with the springs in the soles and I can feel it in those shoes. I don't feel any springs in these at all. Upper part of shoe is well made, but soles are disappointing for a shoe that prides itself on just that feature. The T-strap Spiras I got earlier are dreamy. I only wish that these were as comfortable.
