Came up with new idea for strapping leg fenders to my shins.
The previous concept with the foam cushions and nylon straps was too tight and didn't hold in place when walking around.
Found some used baseball catchers leg guards real cheap for $9 at a Play It Again Sports outlet store.
Going to affix the leg guards directly to the fender plastic inside, which will have a secure and comfortable fit.
I will have to come up with a different procedure to fasten leg fenders when it comes time to suit-up, rather than screwing together the fender in place around my leg.
