Hapad Longitudinal Small Metatarsal Arch Pads are my preferred Pad.
These pads spread the weight over a large area and can be thinned by peeling layers off.
Hapad Metatarsal Pads can be used in 2 directions just before the sore area on the foot. This is the common direction.
This is a common modification of the small Hapad metatarsal pads with the thickest part under the 2nd metatarsal head. These adhesive felt pads also can be easily adjusted.
