Hi bounce
To start with the rubber Hoofs that came with your stilts are not Hoofies

Hoofies are my own design and I invented the name
I take it you have seen the how to about the MK3 hoofies and I counter bore the back bolts to sink them into the rubber
I havn't seen the sort of stuff you are making yours out of but a few tips on suitable material might help you
First it must not give when you pull it as this will just make it pull off of any fixing you use
I used a nylon cloth backed rubber on my early ones and you could put it in a vice and hand your whole weight (17stone) on it without it stretching
I now use new Motorcross/road tyres to make the mk3 and that is tough stuff but still rubbery it can stop 1/4 ton of bike from 70 while smoking

I know I've done it
I tried several sheet rubber materials and they all stretched and came off
You have to get the right mix of hardness to grip in whatever material you choose as too hard (plasticy) will slide even on concrete and too soft will grip very well but wear in hours (I had some stuff that you could almost walk up walls with but it lasted 20 mins and turned to an ice ring with a dab of water)
Have a look at someones Hoofies mk3 next time your at a meet and you can see how they attach as if you can counter bore the stuff you have it may work well
