Always use the product as directed. If the product causes your shoes to stay buckled for more than 4 hours after you've tried to remove them, see a bike mechanic as quickly as possible.
A strap broke on my beloved Sidis. These are a quick and inexpensive save and easy to switch out. i replaced the buckle strap at the same time to make sure I would not have to ride with duct taped shoes again.
I purchased these to go with new straps and buckles on my 6 year old Sidi mtn bike shoes. These compression straps fit perfectly and were much easier to install than I had expected. No tools required and completed the job in less than 1 minute per shoe. My old compression straps were okay, but I wanted to get new ones just to make sure they were compatible with the replacement ratchet straps and buckles I needed. As it turned out, the old compression strap would have worked fine - but these new ones do look much better.
