I purchased this model in particular because I developed an ugly bunion for the past year, and this model does correct the biomechanics of the hallux valgus deformity. I should rather say that it slows down the progression of the bunion, in conjunction with other foot orthotics. Amazon had the best price for this sandal. I definitely recommend this sandal especially for those who developed bunions, but in general, it's a very comfortable slipper.
