ktimmmtbwrote a review of Giordana SottoZero Shoe Cover on March 11, 2016
Familiarity: I've put it through the wringer
Kept me toes warm for rides starting at 30 degrees (despite what the Garmin said), without any real added bulk. Can get about two hours in cold weather before toes get nippy. Read the complaints here about the zippers failing/breaking. I think some care in putting these on will help them last, like pinching the zipper together as you pull up. I put a couple dozen+/- rides on them over the past two NY winters without trouble. I like the sole design. Covers the whole sole underneath except for the cleat and heal pad. One thing I didn’t like about the Gore Thermo (which I returned) is that it’s only an elastic strap so if it isn’t tight around the sole, there’s a lot of space for cold air to come through. If you’re on the higher side of Gores sizing and get cold feet, then I would expect the fit to be better and would gladly pay the extra $40-$50 for what I think would be a warmer cover (but can’t confirm). But for the $30 sale price I paid for these, I am very happy with the purchase.
