Comparison of the ICESPIKE System and sheet metal shoe screws, as tested Pro runners and hikers
Icespike uses a steel composite designed for strength and endurance.
Sheet metal Shoe screws are made of soft metals like aluminum that break down quickly, making them more dangerous on ice and slippery terrain, as they round off.
Icespike’s design, with its deep, wide V groove and sharp edges, allows the spikes to be self-cleaning and stay sharp even as they wear.
Sheet metal shoe screws get packed with debris, ice and snow and become useless.
Icespike's thread design is very fine and its sharp, large serrated washer keeps it in place minimizing the impact on the sole of the shoe or boots.
Sheet metal Shoe screws have no serrated washer to hold them in place and their thread design is rough which can damage the sole of the shoe or boot.
Icespike will last up to 500 miles making it unnecessary to your shoe screw over and over again.
Sheet metal Shoe screws need replacing frequently and take time away from your favorite outdoor activities.
