Shamelessly namechanged as I don’t want rancid feet to be linked to my other innocuous posts 
Posting here for traffic mainly as I thought I’d consult the infinite wisdom of AIBU to tackle this issue.
My DP’s feet stink. He showers twice a day, wears clean socks every day. He leaves his work boots at work and changes into a pair of trainers to come home in. He has a very physical job and is on his feet all day. But when he comes home, the whole place is stunk out by his feet and these horrific shoes! We’ve tried tea bags, bicarb and the most offensive smelling trainers are currently going round in the washing machine.
He gets very upset if I mention that I can smell his feet, as I think he’s actually quite embarrassed about the problem.
How can the poor man stop his feet and shoes stinking to high heaven?! They actually smell like a dead animal, and the laundry bin smells even worse when it’s got a few days’ worth of socks in there.
TIA
