+2 for Speedplay Zero. The mechanism is simple, with the only moving engagement part being the clip which is held in the cleat. Cleats are a bit pricey as a result, but since they have a metal bottom, they last much longer than the Look nylon ones I used for many years. In >16K miles, including some city/surburb starts and stops, I'm only on my second set of cleats.
Never walked in snow with them, but getting mud or sand in the cleats can also cause the clip to stick, making engagement/release difficult or impossible. Fortunately, the easy fix is to carry and use the "Coffee Shop Covers".
The bearings must be tiny, but holding up well. Factory says to lube the bearings every 1-2K miles, which is a 5 minute job with a mini grease gun.
