I only wear my Tuxedo shoes a couple of times a year, and I worry about them getting crushed in between. I'm a size 14, so the XXL barely fit, but that's what I wanted. I cleaned the shoes, put these in, then slid them into old cotton socks to keep dust off and put them away. My only concern is a small one, there did appear to be a couple of spots where sap was coming out of the wood...I'm hoping there's not enough to damage the leather.
