TCX Shift Guard - Boot Protector From  £6.99

This looked great and the perfect thing to stop my lovely biking boots getting damaged. It slid on easily and seemed quite tight but within 2 steps, it had come off. I didn't even try it on the bike. Complete waste of money. I think these things only work if there are laces on the boots to secure it and most biking boots are not lace up. It is currently sitting, redundant, in my top box :0(
