Tornado Rain Gel Crutch Tips have all the same great qualities as the Tornado Tips, but with highly improved slip-resistance in wet conditions. Tornado Rain Tips have a rain disk formula bonded over the tread making them over 300% more wet slip resistant. They have excellent traction on dry surfaces as well. They use the same Absorbalite ™ gel core that provides a shock absorbing system. They are made from high quality rubber that has superior flexibility, aggressive ground engagement, and extremely long wear. The engineered pivoting action enables more of the bottom to engage the ground for amazing traction, even at very steep crutch angles. They have a 2" base diameter and weigh 4.6 ounces each.
