The Petzl Spiky Plus is a rubber sock that fits over your boots and has six carbon steel pins or spikes that provide grip on the ice. These are very easy to fit, and they go over your shoes rather like slippers. They also stay on the shoe very well, thanks to the large area of rubber that isn’t so stretchy that they just roll off all the time. There are cut-outs on the heel to allow your boot lugs to provide extra grip, but in the forefoot area the sole is completely covered by rubber, so you’re more reliant on the spikes. The spikes are only 2mm long, so they certainly won’t bite through soft snow to a layer of ice beneath. There are also only six spikes, so grip is limited on uneven surfaces and your boots will be too stiff to allow all the spikes to come into contact with the ice at once. I’ve used these on level frozen paths and they do work okay, but they require far more careful foot placement to ensure the spikes are biting in. As a result, they have much more restricted use than other options we tested.

The Petzl Spiky Plus works okay on level surfaces where there’s a thin layer of ice, but the grip is more limited than with other options.
