I've done basically the same thing. Definitely passes the sniff test - somehow there's not much of a difference. Not sure if oil from the skin ends up becoming a antimicrobial agent over time?
FWIW mine need a wash after ~4-6 wearings or they smell. I haven't tried the vodka-spritzing trick I've read about, though, which may let them go longer.
How they're stored probably affects it some. I have better results hanging them up rather than letting them sit on the floor, even if I'm just going to put them back on the next morning.
