Thorogood’s (VGS) Visible Gel System adds state-of-the-art cushioning to lightweight performance footwear. Absorbing shock with every step, the inter active system improves comfort and reduces repetitive impact stress where its needed most – in the heel. The unique VGS gel heel unit will not deflate like an airbag and never loses cushioning power. It has been tested to withstand 300 foot-pounds per square inch versus the standard 75 lbs of pressure resistance available in competing footwear. Adding to the comfort of this breakthrough footwear is a single density polyurethane memory foam removable footbed that cradles the entire foot and enhances breathability.
