I could not imagine doing any hiking or climbing with this design. 5 asics all the time and these were just a bit tooo snug. - With both straps being too tight, it prevents the foot from going forward enough to wear properly, causing your heel to be too far back in them. to sit on it for putting on shoes! Im not hearing the birds or other normal surroundings. The loop hook come in handy when traveling light. Unfortunately, I was not able to evaluate long term durability and comfort, but I like overall design and magnetic buckle. Still totally worth it. The strap here could be softer or wider or a wee bit higher for comfort but thats what I expect keeps the shoe on. I hope they will get a bit larger by wearing them.
