I was always skeptical of Nestor's true ability to fit boots. But I'm sold. I bought some tight ass race boots, and after working with them, they're almost perfect. I never thought I could fit in a boot this small (street shoe is a 12, ski boot is a 9.5) but I love the performance. I just got new foot beds, and with some adjustments to the liners (adding more padding, actually) I think I'm a visit or two away from perfection.
