Familiarity: I've used it once or twice and have initial impressions
Regret spending the money for these thingys. Rode for three hours today in mild conditions (high 40's an light rain). Toes were cold and wet by the end. Really no idea what these are for. Will look for winter shoes instead. At least they appear to be built nice.
