Choose the Merrell Moab 3 GTX if…
…you want a sturdier sole and more protection than a trail runner for day hikes and lighter backpacking, without the weight of a boot.
Choose the Topo Athletic Ultraventure 4 if…
…you move fast on trails, run some of it, and want the lightest and most flexible shoe; it gives little ankle support under a heavy pack.
