Yes, the sensation of burning feet is often caused by compression in the area of the metatarsal heads, as nerves and blood vessels are compressed there. By optimizing the foot position, SOLESTAR counteracts the feeling of burning feet. This is because the very torsionally stiff SOLESTAR insole allows little movement in the metartarsal head area (forefoot) and therefore reduces pressure on the structures that may be overloaded.
