I've bought three pair of Z-coil shoes from Darlos over the last two years. I am so impressed by the owner who gives you the same great service each time and doesn't try to sell you anything, but helps you figure out what you need. He also did a great job of explaining what I needed to know about my Z-coils. Like how to tighten the spring. Personal service like it used to be and still is at Darlos.
