If you haven't had a ruptured disc and droop foot, it's hard to understand the issue.
I blew a disc and was in tremendous pain. I went to the doc and it was a wait and see for me. I still have the blown disc that's like eating a jelly donut and have the jelly squirt out the side and just stay there. This was back in '00 and it's eventually gotten better, but I still have a slight cadence difference if I'm wearing hard sole shoes and walking on a hard surface, you can hear the difference between the two feet.
In my case it was my right foot. I had just finished my '40 Willys coupe and when driving it to let off the gas I had to literally lift my whole leg to slow down. I could not lift my toes with any force at all. Most people can stand on their heels and have the ball of their feet lifted up off the surface. Even today I can only do this with my left foot. My right will still have just a bit of down pressure. Just after the blown disc and a little rehab, I went to many car shows. Most were in mowed grass lots next to larger venues. When I walked around early I'd get back to my Willys and my left foot would be nice and dry, but my right foot would be all wet on the toe and top of the foot. The foot was dragging in the dewy grass.
So for the OP, raising the toes is impossible. The ONLY option is to use the heel shifter and for him it's lift the whole leg to do it.
I agree with the heel resting on the shifter after the shift, it will wear out the shift forks. In the old days with floor 4 speeds, a lot of people used to cruise with their hand on the shifter. It was a great source of income to the dealership I worked at. It took out many shift forks.
On my old '76 FLH, the 4 speed has a VERY long shift stroke. I used only the toe for years and always had to lift my leg to get the up shift to happen. I just recently went back to a toe/heel shifter and it's MUCH easier to shift the old best.
Sorry for rambling guys...
