Bought it for my GF, a size 9. The longest mounting bar BARELY worked on mine and thus it is secured unreasonably snug against my spare which will likely create a permanent imperfection in the tire (not a huge deal but another 1/4 inch and this would have to have been returned). Just be clear, the light itself can be a powerbank and power your phone while lit. While I wish the supports on this were flat there is a non slip material that holds it in place. 5 out of 5 This perfume cannot even be detected after 20 minutes. It uses a USB-C cord to charge and comes with an actually decent cord. I definitely think soundpeats could reduce the height of it though as there seems to be plenty of room in there to do that. The only way to half way wear them is to put a bandaid on the back of each heel. The Acorns fit so well and maintain their shape MUCH better.
