You'll just want to leave them ON - these shoes are EPIC!!!
I absolutely adore these shoes. I usually run between 40-60km per week, and got them for training in. It's now difficult to get me to take them off!! I had started to develop pain in the ball of my feet. Towards the end of longer run, I would usually have shin pain and sore feet. The ON Cloud Ace has solved this for me. Surprisingly, on longer runs, they feel faster to me than a minimalist shoe (like the Adidas Adizero), as I don't lose pace due pain. They simply eat up impact. I also pronate a little when I run - these shoes are beautifully stable. The quality and engineering in these things is wonderous, and completely worth paying a little extra for. Honestly, they feel like the running shoe equivalent of stepping into a Bentley. Don't think twice about getting a pair, your joints (and running times) will thank you. Thanks On for building an awesome product!!
