I was searching for a boot that would have some good grip on the ice surface of the arena i work in, and after discussing it with the customer service person, she recommended the rubber outsole, I should have selected the TPC outsole.
These boots not only do not resist slipping on wet ice (very slippery) but they also do not help with slipping on dry, and snow covered ice.
Boots are comfortable, and aside from the zipper (poor quality) they seem to be ok otherwise.

Light weight excellent boots needs to be worked in insoles leave a lot to be desired bought new insoles

This is my first set of sidewinder and love them.
Warm, great support and comfort
