After 3 years my Sidi Dominators were getting harder to buckle. I ordered these straps, got them the next day, and installed them in under a minute. The shoes are as easy to buckle as when they were new, and my shoes feel new again.
The caliper buckles shipped are not the ones pictured. The ones pictured (and I needed) have a narrower ratcheting band down the middle. The ones shipped have a ratcheting band all the way across, and do not fit the newer caliper buckles (the ones I also ordered).
Bought these in combination with new buckles to breathe new life into my old Sidi mtn bike shoes - which are at least 6-7 years old. These new straps were completely compatible and extremely easy to swap in for the old ones. No tools were required and it took less than 1 minute per shoe
