While zero drop and barefoot style boots may be a small market segment, it is definitely big enough to support launching a quality product. The only options available are either poor quality and not made to hold up long term, or they are not designed for use in rugged mountain terrain.
I could almost guarantee that the majority of biomechanical issues are due to people being out of shape, unhealthy , and/or a lifetime of wearing foot casts which causes poor alignment, weak lower leg/foot muscles, as and poor mechanics.
Years of sitting in chairs and wearing thick-heeled footwear shrink our hams, glutes, calves, and all the connective tissue. Deep squats to stretch out and strengthen plus barefoot style footwear are the fix
