Hate to break it to you but the shoes are ready for retirement. I had a pair of those aswell, back in the 80s. They were great I only had Sidis untill the beginning of 2000 when they did something to the tongue that made them uncomfortable for me. Now i use nothing but shoes with BOA and wouldn't use anything else. Great bike btw. I also had a Peugeot 531 Pro frame in the 80's, in black, very good value for money and i ended up crashing that aswell, in a race. Hope i haven't hijacked your post. Didn't mean to anyway
