They're a year or two old, but have only been worn on two trips by my son during spring turkey season. He outgrew them quickly and they're too small for me. They're waterproof, breathable (DRY-PLUS layer keeps feet dry), Scentmask technology to reduce odors, and lined with Thinsulate Ultra Insulation.
Size 13, but they run a little small for 13s. If you're between 12-13 they'd be a good fit, probably closer sized to most 12s. Well over $100 new, I caught them on sale for $80. Asking $50 OBO in DFW area.
