Stump Armour is finally live on Indiegogo. It is a low cost multi purpose stubby foot for double above knee amputees. It's used for climbing, rough terrain, ladders, construction, and a myriad of other tasks. Check it out and if you can spare a buck all contributions go towards FREE FEET FOR AMPUTEES that need them. PLEASE SHARE. There are sponsorship options for companies too.
I've seen what you're doing. I've shared the info on my Twitter and Facebook timelines.
Let me know if you need a crash test dummy.
