The TREX 6310 Adjustable Slip-On Ice Cleats are lightweight ice grips for boots and shoes that provide tenacious traction and extra stability on ice and snow. Stretchable one-piece design offers grip to prevent slip and fall injuries on the ice. These ice grippers feature 10 rugged carbon steel cleats on the ball and heel of foot for grip on slippery terrain. Aggressive trade connects mid-foot and heel stud zones for extra traction. Available in multiple sizes and will fit over any style of boot or shoe for traction and stability during winter work or other winter outdoor activities. Tested to be flexible in temperatures down to -40°F (-40°C), the stretchable rubber material provides a secure fit and easy slip-on/off wear. An adjustable cord cinches tight for a secure fit. Reflective pull-on tab on these ice traction cleats adds enhanced visibility. These snow cleats are lightweight and can be folded small enough to be stored in a pocket or pack when not being worn.
