Hi guys, brand new to the forum, very enthusiastic to join the community. I know exactly what i need printed, orthotic shoe inserts, but before i invest in my first printer i was hoping some of you could weigh in what you would believe to be the most appropriate material to use. I need it to be strong but with some flex, resist warping, and be ok getting a daily beat down by the bottom of somebodies stinky, sweaty foot. Most of my research has been focused around makerbots offerings and ny humble opinion would lead me towards a PLA filament but am concerned potentially about the brittleness and susceptibility to humidity. Pulling from your experience and knowledge would anyone please share their opinion on print material and\or suitable printer options? Any and all steering is appreciated.

thanks!
