The Shimano R320 and R 260 come with moldable soles pictured here. The bottom has a optional metatarsal stick on pad and has a sleeve for arch pads. You can adjust the arch for 3 levels of support with insertable pads also pictured here. You want as much of the bottom of your foot to contact the sole of the shoe to evenly distribute pressure reducing the load on the forefoot which will cause hotspots.
