hey if you want I can send you some pics of how the brackets are made I can show all angles. If you have anykind of sewing experience it shouldn't be a big deal. Just the hardware and a person to fabricate the bracket. Duct taping is a bad idea if it falls off your foot it could do property damage and maybe kill someone. so if your deadset on jumping smoke email me and I go into better detail on how to build them. I have made over 20 in the last two years. I can't sell you one but can help.
