In the past when it gets between about 35 and 45 (F), I often put a scrap of plastic from a shopping bag over my sock in the toe area before I put my shoe on, that is intended to block the wind that comes in thru the shoe mesh vents. But not a full plastic bag, I want them to breath, so only over the toe area. Below about 35 (F) I used hiking shoes, but I got these shoe covers to try to extend my cycling shoes to lower temperatures.
