The LET glider is a resistant insert designed to have good anti-slip properties. The base in contact with the ground is made of Polyurethane (PUR), a material that is highly resistant to deterioration, scrapes and traction. It also has good cushioning capacity and flexibility even at low temperatures. Regarding chemical properties, it is very resistant to fats, oils, oxygen and ozone.
The body of the glider is manufactured in PA6 (nylon) and not in LDPE as usual, which makes it more rigid and provides good mechanical behaviour.
