Thanks to the new design technology used for the sole and breathable perforated toecap, the line of STS (Super Trail System) footwear is now lightweight with a sporty look yet still offers the same safety features and comfort.

This line of Grisport Safety uses the innovative Boa Closure System. With nearly 14 million Boa dials worldwide, the award-winning, patented Boa Closure System is reinventing how footwear performs.

The STS line is designed with a Vibram sole that has important features: Flex line for natural rolling; different material density for outsole arch stability and comfort; engraved shank (90° profile) for better traction on uneven ground; draining channels to enhance grip and safety; spider design for axial guidance and control; large toe and heel lugs for grip on multiple terrains.
