It is reinforced with the TrailProtect pad—another Merrell-exclusive technology that adds a layer of terrain protection for the user.

The MQM Flex GTX is capable of stabilizing the foot over uneven terrain with ample cushioning thanks to its FLEXconnect dual-directional flex-groove EVA midsole. Its forefoot has vertical grooves that allow the midsole to flex with better fluidity, giving hikers a sense of connectedness to the ground.
