Thomas, that was a really good question. Not a question we ask ourselves here in SoCal very often. Granted we just saw some light rain yesterday my go to are a pair of leather upper Nike Cortez (Forest Gump colorway) or my (Supreme x Nike) Humara’s. Both very comfortable, stylish. Cortez a runner and with leather upper, does a good job at repelling water. For heavier rain I go to Humara as it’s a trail inspired with a higher stance. The leather and nylon upper does a great job at keeping the wet out. Also my go to when I’m in snowy climates.
