what kind of material does my boots have ? does anyone know? it feels like suede but i don't think it's suede. asking because i just bought a waterproof/polishing wax called "tana dubbin graisse", not sure whether it'd kill the surface or not. also, would it be possible to maintain the boots such that the creases (the front part where flex occurs) are minimized/reduced ? anything i can apply to reduce that appearance? thanks!
