My name is Thomas Fetterman and I have used crutches for the past 58 years. 21 years ago my doc told me to use a wheelchair and give up crutches because my shoulder pain was unbearable. Instead I invented Tornado Gel Filled crutch tips that have a built-in shock absorbing system. Within three months of use my shoulder pain dissipated and I have been relatively pain free for the past 20 years! And the traction and durability of Tornado Tips is unsurpassed in the industry. Over the past 20 years I have received hundreds of "thank you" testimonials for which I am very grateful. As much as Id like to say that I was thinking of them when I developed Tornado Tips,I really was just worried about myself and how to reduce my pain and extend my mobility... Viva Tornado Tips and vertical into the future!
