Metal cleats affixed to a rubber covering that can be attached to a shoe.
Ice cleats are a device, affixed to a shoe or boot, with small studs or spikes underneath. They are used to avoid sliding on slippery surfaces like ice or snow. Ice cleats are attached to footwear with either straps over the heel and toe or a single strip over the foot. Not to be mistaken for crampons used for ice climbing, ice cleats are much smaller and are commonly used in arctic areas.
