Sole for footwear used on slippery ground - has flat studs on back and front separated by grooves that push liquid away

摘要

The sole is for footwear worn on smooth and slippery ground on which viscous liquids are spilt, such as in the foodstuff industries. It has studs (4) which are flat and have sharp edges. These are separated by grooves (5) which push the spilt liquid towards the outside of the foot. The studs are on the front (1) and back (2) of the sole and between them there is a wide groove (3) corresponding to the arch of the foot. The studs on the front are in staggered rows (40,40',41) to guide the liquid outwards.
