These sandals have a really cushioned foot bed so are ideal if you have sensitive feet. The upper strap is fairly high up on the foot so will help to hold the foot in place and stop it sliding forward, particularly if you are slightly narrower around your heel. If you have a lot of swelling around your heel, you may find that strap too high and would perhaps be better with a different style such as Sunny.
