Very happy with the crutch although the additional padding provided for the forearm cuff does not stick very well even with using the 3m tape. I used doubles side tape. Hope it works.
I'm 6'5" with big hands and also have RA and some upper back arthritis. First, these poles are an instantly more comfortable for walking than using a cane! It's easy to keep my head and back upright and the stability of the poles is really great. They weight about 5 ounces more than standard poles, and I definitely feel more stable while I'm using them. The push button height adjustment is very easy to use, too. The palm cradle gives an extra level of comfort while in use. I'm absolutely sold on these poles, and if you're over 6'4" and/or have very large hands, you'll need to try these out. You'll be impressed, too.
With EDS I had no idea how badly regular forearm crutches would hurt my wrists and hands. These are all I can use with both knees doing poorly and I’m so happy they exist. Thank you!! The space pattern is awesome taboot.
