There is a breakin period where the shoes are uncomfortable and my Achilles' tendon was sore and needed bandages. I've had them for 2 months now and worn them for maybe a month total. They are getting more comfortable and I have to make sure I wear a higher cut sock. Ankle socks will slip down with each step and that's very annoying. I would recommend these shoes as long as you wear ankle socks and not no show cuts.
