A squeezed foot gets cold. - Waterproof socks keep slush out but trap sweat, so save them for wet days. - Toe socks prevent blisters between the toes for some runners. ## All 5 socks ### Smartwool Run Cold Weather Crew Socks (Targeted Cushion) $24 list · Unisex, Women's · Midweight · Best for cold runs Smartwool's winter running sock adds crew height and merino warmth to its targeted-cushion design. 220 Triathlon found it very warm and comfortable, and still warm when damp, but pricey. - **Best for:** Below-freezing road or trail runs, especially in tights, where crew height protects the ankle gap. - **Not for:** Mild-weather runs, or slush where a waterproof sock is needed. - **Downsides:** Costs more than basic running socks; Too warm for mild days; Not waterproof - **Full brief:** https://agenticrecs.com/products/smartwool-run-cold-weather-crew-socks/ - Smartwool: https://www.smartwool.com/en-us/products/run-cold-weather-crew-socks-sw001905 ### Showers Pass Cross Point Waterproof Socks: Sport $52 list · Unisex · Midweight · Best for slush Showers Pass's athletic waterproof sock puts a breathable membrane between a knit outer and a terry-cushioned CoolMax liner to keep feet dry in puddles and slush.
