Old school: The only way to get big support is with big boots. New school: Combine innovative design with lightweight materials, and go to the head of the class. This model employs a hinged plastic cuff to deliver superb ankle support without clunk. Our tester reports: "Super comfy on the trail, thanks to generous forefoot flex and a well-padded upper. A rigid sole and grippy traction let you veer off trail with confidence." Best for medium-volume feet.
