I’m an amputee how well do magped pedals work? What is a good shoe?

I have a transmetatarsal amputation. I'm missing half of my foot and I don't really have a lot of feeling in either foot. So you can imagine my feet constantly fly off the pedals and the spikes cut me up pretty bad sometimes.

I don't have a lot of money but I'm willing to splurge on these pedals. (They will cost half as much as my entire bike).

But I need to know will they hold my foot on the pedals? Will they last me a few years? I mostly do gravel riding 1000 miles a year. Id like to do slightly more aggressive trails though if I could keep my foot on the pedals.

Anyone have experience with these?

Thank you kindly.
