Used in hiking shoes and working well. Love the grip!

Used these in the front tire of my girlfriends yz85 lasted all winter riding single track in the woods!grip good for what they are

I was looking for some studs to make some "no slip" boots. These screws are great. Although a bit of a nuisance to put together, the 3/8" screws can be driven into the soles of hiking boots, or heavily soled runners to create some dedicated footwear for those super slippery days ... much better than taking a chance of a fall and/or injury while out for a jog or a dog walk. Some enterprising folks have put a few of these together and marketed them as a "kit", but at a much increased price point.

Excellent screw head design for general traction use.

Super produit, tres facile d installation et ca mort dans la glace
