The M3100 reinvents the classic boat shoe by incorporating all of MBT's innovation. Behind its elegant and timeless look lies the Modena rocker sole, designed to improve posture, reduce pressure on the joints, and activate muscles with every step. The pivot point provides a pleasant massage sensation under the arch of the foot, while ankle support and premium cushioning ensure stability and comfort throughout the day. Its adjustable lace-up upper and refined finishes—raised welt, discreet stitching, and crafted collar—add character to its design. With its memory foam insole and MBT® Sensor technology, the M3100 combines nautical style, long-lasting comfort, and biomechanical well-being, ideal for elegant and healthy everyday use.
