LD Mountain Centre Says:
Add years to the life of your ski boots with Cat Tracks. These handy rubber treads fit easily over the sole of your ski boots to protect the heel and toe areas while walking around resort on tarmac. This means the areas of your ski boot that fit into the binding don't get damaged.
Seirus Cat Tracks Features:
The Seirus Cat Tracks are compact, non-slip, pocket-sized boot protectors that stop you slipping-up on the way to the lift and prevent your boots wearing down whilst walking on the pavement. Highly recommended for prolonging the consistency of your binding release.
They do everything they promise: Protect the soles of the boots, increase grip (on all surfaces) and make walking more comfortable (give a cushioning effect). I've tried other types over the years but Cat Tracks are the best and the cheapest. They are pocket-sized but I don't like my pockets to be stuffed full and pockets space is limited so when I get onto the snow I loosen off my power straps and loop a cat track over each one before tightening the power straps right up - that way the cat tracks are secure and hidden inside the powder cuffs on may salopettes so my pockets don't get wet like they used to when I forgot to bring a plastic bag to put the cat tracks in.
Bought these to protect new ski boots. Relatively easy to put on/off and certainly protects. Walking was also easier especially on snow/slush and didn't slip on the wet ski bus floor. Highly recommended.
