Fit Guide
Size guide.
WorkAssist socks use a Japanese fit system. They run slightly snugger than North American socks — that’s by design. A tighter knit holds the arch support in place.

Sizing tips
Between sizes? Go up. The knit will conform to your foot over the first shift.
5-Toe line: Same sizing. Toe sleeves stretch to fit — they feel snug at first, then natural.
Steel-toe boots: Don’t size up the sock to compensate for a tight boot. The sock should be snug; resize the boot if needed.
