Creating a metatarsal support button on the bottom of the shoe insert is easily done with duct tape, which happens to be the method I used to address it in my shoes. This usually helps considerably with hotfoot.
What I have seen with arch support is that it falls short in fully addressing hotfoot, and should be used in conjunction with a metatarsal support. Arch support does address vargus and knee alignment. It comes down to proper support of the foot in the shoe for the job it is doing.
