Abstract
The invention involves a tread system for shoes More specifically, the present invention is a tread combination that is particularly suited to work environments where the workers are required to use a walking gait upon slick floor surfaces, some of which may be partially covered with liquids. The system includes an outsole having a heel strike tread having a pointed leading edge with sipes for squeegeeing and channeling liquid away from the center portion of the tread to prevent forward slippage. The mid and forefoot portions of the outsole are provided with cross siped treads which reduce or prevent sideways slippage of the forefoot.
