I bought them off of Amazon who will take things back no questions asked (as I'm sure you know. I drop off random fishing stuff at the Kohl's drop off all the time; they take it all no questions).
I wear a pair of wool socks and tech pants beneath the tidewe waders and again, I'm just amazed at how warm they are (granted, standing in water for hours on end eventually my feet get a bit cold but it's never unbearable; those toe warmers things would probably help a ton but again, it's all very bearable).
just can't beat the price, too.
