Puma — brand new shoes i cant wear

I got a pairpair of pumas for my birtday fRom my son, I don't have the heart to tell him why they still look new, is because they make my feet sweat so bad that I got swomp feet not swomp foot. They hurt so bad I couldn't walk for two days after wearing them, my feet stink stink now and I have never had problems with my feet.I am on disability and cant afford aanother pair and when I tried to return them the store wouldn't take them back because they were worn. I love the shoes because my husband wore pumas we have been together for 30years and those are his favorite shoes.so this was my first pair .they are light and beautiful but no air goes threw them. IsIs there something I can do so I can get a pair I can wear these I wore 3 tImes and can't wear .they hurt my feet and the shoes smell so bad .thank youmrs olive klassen
