There is no way to ?secure? your rack system but if they want to steal the mounts themselves, they?re gonna need to work for it. I have been wearing Asics size 9. I have problems with my feed and need a slipper with cushion in the sole. 5" long heel to toe and the size 11 was way too small. Velcro strap tore off on one pair. I also wore them to ride my motorcycles, Buell sport bikes, not cruisers. 1/25/2021. I?d highly recommend them for your summer wardrobe. Perfect size to organize spices in pantry. Finally pull this tool off the shelf and out of the box .
