Performance RT (Rain Tips) Performance Rain Crutch Tips give you the same shock absorbing qualities, superior flexibility, better ground contact and longer wear as our original Performance Gel Crutch Tips with improved slip-resistance. My patented Performance Gel Crutch Tips have a thick shock absorbing Absorbalite gel core with our new gray slip resistant rain disk bonded over the tread making them over 300% more wet slip resistant than any rubber tip we have tested. They have excellent traction on dry surfaces as well. The addition of the Rain Tip will only increase the height of the tip by 3/16" While not slip-proof, the Rain Tip will greatly reduce the number and severity of crutch related falls caused by wet smooth surfaces. If they keep you from falling just once a year wouldn't they be worth the extra cost? Personally, I won't leave home without them! The Performance Gel Crutch Tips have a larger base diameter and more shock absorbing gel, but are a bit heavier than our Tornado Gel Crutch Tips. Performance RT tips have a 2 3/8" base diameter and weigh 7.1 ounces each. Fits crutch shafts from 7/8" to 1" Sold in Pairs Color: Black Search "Fetterman" in Bonanza to see more of our quality crutch and cane accessories.
