I was thinking of the STS net too but can see what you mean about needing to be uncovered under the net and having the net against you feet and legs. Be a regular bug buffet!
Maybe get some small carbon fiber kite tubes and make bottom corner struts to suspend the bottom corners of STS net? DO you still have the one you tried? You could maybe use some dcf repair tape to make a top cap to hold the top of the struts or make a short sleeve and run cord through the strut and stake it out tight like the short struts in MLD innernet floors.
To further clarify I’m thinking about something like rolling say a 10″ strip of the repair tape with the sticky side out into a tube. with the strut inside it so the tape has some substance to form against, then take 2 more 10″ strips and glue the tube at the correct location to make a bottom corner sandwiched between the 2 strips of repair tape; one on either side of the net. That would form a corner seam and dcf tube for the strut and the strut could be removable. Or if you have a machine and can sew…. which I obviously don’t have and can’t do….Then run some like 1.7 or light cord through the carbon tube to make a stake tie like the one shown in the MLD innernet. The struts on either side would provide the side to side tension and elevate the net. Maybe they don’t need to be 8″ or maybe they need to be longer, and you probably would need to make sure there was end to end tension as well. Maybe a second guy line from the top of the “pyramid” running away from the bottom corners. Then the net would be tensioned up, back and at the corners of the foot.

Take some fiddling but once you got it right it ought to work pretty well.
