Cleats

Source Advanced Player’s Guide

Useful on any terrain where traction may be a concern, cleats are shoes with spikes or hooks attached to the soles. Cleats reduce the penalty for walking over slick surfaces by 50%; for example, walking across ice normally costs 2 squares for every square of movement, but with cleats it costs only 1.5 squares for every square. Cleats cause damage to any type of finished flooring.
