I’ve used these just the once on my chpt3 Brompton with flat pedals and that’s it. Never had cleats fitted and apart from minor soiling to the bottom they are absolutely mint. Sizing wasn’t quite right for me so they went back in their box and I forgot about them until just now. Super rare as chpt3 went bust shortly after releasing these, so grab a pair while you can! Will come in their original box and with a pair of socks which were gifted with them.
