Cheapest place to get custom orthotics online?

I actually tried Upstep a while back and they turned out way better than I expected. The process was super easy, they send you a kit to mold your feet and then make the orthotics based on that. Mine fit really well and honestly made walking and running feel way more comfortable. I was kinda skeptical at first but they held up great and felt solid. If you are looking online, Upstep is def worth checking out because the whole experience feels simple and reliable.
