Merrell's leadership in the barefoot category continues with the Trail Glove 7. Key factors include more natural foot positioning for a true minimalist feel, a Vibram EcoStep outsole that wraps the foot to maximize grip and connection, and a minimal midsole made of FloatPro Foam, Merrell's best midsole foam. Within the midsole, we also integrated Merrell's FLEXconnect dual-directional flex-grooves for enhanced ground connection. Total stack height on these shoes is 14mm.
