How do I get rid of SEVERE athletes foot?

It doesn't sound anything like athletes foot to me.

It could be psoriasis, which is treated with cortizone type cremes - have you tried those?

But one simple thing that can help a LOT is white, zinc diaper creme!

Buy it in the dollar store and use it all over for a week - you might be very surprised how much better it can be.

Then you can always use the coritizone creme later if that doesn't work.

first, soak his feet in cheap vodka or everclear. Let them air dry. then add turmeric, ginger and cloves (all powders that you can get from an indian store). You can keep this mixture for several days, and it will turn your feet yellow. This helps you know that you got the medicine everywhere! also, use neem oil on the dry feet, and never wear the same pair of shoes more than once every 3 days. also spray the shoes inside with Lysol.

ok you need* prescription antifungals. do you have a friend with insurance? Here's what you do. they need to have red skin somewhere near their crotch or toes and tell their doctor they tried OTC treatment.

For the red skin you could use dye, raspberries, elderberries, or just scrub really hard with a luffa or something.

*I mean need need... like have you seen pics of people in third world countries with out of control fungal infections?? that's where you're headed and fast.

good luck!
