ordered these without checking the size I needed, like an idiot. I don't know what shoes take an m4 bolt, but they are certainly not mountain bike shoes. I'm trying to source some m5 x 9mm bolts now with the head profile speedplay frogs require and its a nightmare. use locktite so you don't lose those precious bolts because shimano bolts don't work!
Pros: they are what they say they are
Cons: they do not fit speedplay frogs
