Haven't used the shoes. Bought a pair by measuring my foot and adding 1cm, they were wayy too big, so I returned them for a smaller size that should have been a snug fit, instead they are again far too loose on my foot. Really disappointing purchasing experience for an online store and don't have shoes that I can wear as they don't fit my feet and slip off with every step.
I'm so happy with my purchase - BPrimal have an awesome exchange system where you can lodge an exchange online and send the shoes back. I had to exchange mine for a smaller size. These shoes are really comfortable and give my toes lots of room to move.
