10 mins tops! Saw they had good ratings on several review sites. 25 inches from heel to toe. The above wouldn?t allow me to give 0 stars so thus I give it 1 star. It fits very loose around the heel and even with the ankle strap, I feel like my foot is coming out of the sandal. They are not connected so you can hang side to side or one on top of the other . I got it up to 65 that time Before the hum began. If you have a quality tool like a Makita track saw, you dont want to handicap its performance by going cheap on a necessary accessory like guide rails. One of the covers did not sit properly after the installation. Easy to walk.
