A new prosthetic foot

im 19, im a right below knee amputee. i work and try to get by just like anyone else. i lost my foot at 12 due to a club foot and surgeries not working quite as easily as they should. i have prosthetics now, but not any that fit or work the way they should. my prosthetic at the moment fits terribly and causes many problems physically. i would love to have a foot that i can work and run and play and swim in.  anything helps and this is honestly a last resort kind of thing.
