Although dad jokes and dad jeans are decidedly uncool, dad socks are having a moment. Socks that hit at mid-calf began to emerge on Fall 2017 runways and are making a strong showing for Cruise 2018. Intarsia patterns look particularly appealing,  but novelty also comes from sparkly accents, brushed yarns, colored marls, fair-isle knits and sporty stripes. Neutrals and brights both work, especially when color is matched to shoes.
