I just read through the whole Dr Sole Maker profile and the whole backstory of the company seems inaccurate. For what they do, some of it is correct, like referencing their Game Changer boot. But they have since launched their own brand called Pioneer. So unsure if this whole Maker should just be changed to "Pioneer" or "Dr Sole / Pioneer".
They are from Taiwan, manufacturing their incredible rubber soles in southern China. A good source of info for this brand can be found here:
