The shoes are very comfortable, however after a few months the inner heel material on both shoes started to fall apart. And that only comes from walking, not running. I have been using a pair of Brooks Beasts to golf for 2-3 years and none of the heels on this pair have worn. I called GDefy to try and get a warranty claim but since I bought through Revain they said to contact them. I just tried to get an A to Z guarantee through Revain and they said the shoes were bought too long ago. Honestly, what does that have to do with anything? I have used the shoes sparingly and the durability of the shoe is obviously in question. Comfortable shoes, just hope your heels don't fall apart after normal wear like mine did.
