A key comfort feature of the XPX763 is its contoured removable orthotic TPU insole that is excellent for those seeking arch support. The polyurethane material used in its insole is known for its cushioning while not bottoming out features. The rigid TPU material helps provide underfoot support in the arch area.

In addition to meeting the highest ASTM F2413 Impact & Compression standards, the MICHELIN® XPX763 work boot also has an ASTM F2413 compliant metatarsal guard helping provide extra protection to the instep area along with the toes.
