After your trek, all those frozen, snow-jammed buckles can be difficult to undo. Newer versions have simpler bindings, much like those found on skis. You can just clip them in and go. When you're done, just kick them off and stash them in a closet or corner. Getting them on and off is easy.
Maintenance is easy.
Using them is easy. Mr. Ridley said. Kids can do it. Parents can do it. Grandparents can do it.
