Expert Reviews

  • The anti-balling system prevents snow from clumping to the bottom and preventing traction.
  • Works well on ice and on slopes up to 50 degrees.
  • Only takes a few seconds to put on and cinch around boots.
  • The crampons do not slip or have any give.
  • Protects against corrosion, promoting the durability.

Reasons NOT to buy:

User Reviews

  • The least amount of grip is in slush.
  • Since it is made of steel, it is a bit heavier than lighter but less durable alternatives.
  • Since the strap runs through the toe cap, it may wear over time.
