Ice Gripster Treads Nonslip Traction Cleats for Snow and Ice, Anti-Slip Overshoe Crampons with Adjustable Cinch Cord, 10 Carbon Steel Studs for Secure Grip, Extra Large, Black and Red

After only a week or two of use I noticed several spikes fell off, that plus I always had a hard time keeping the front (toe end) part to stay on my boot. My boot would a lot of times would end up going through the front after wearing for a while.

So, just got these in. The rubber part that goes over the boot looks great. Unfortunately, they were missing 7 out of the 20 spikes. Not only that, but the spikes that did come with it looked uses. The red plastic is was worn, and the metal spike was rusted. Without good spikes, they are not going to work as well as they should. If you buy this product, you might want to buy extra spikes.
