Counterintuitively, thicker socks may make the problem worse. If the sock is too thick for the boot, it restricts circulation, which makes feet colder. The most common causes of cold feet in kids are: (1) socks that are too large and bunch up, restricting blood flow; (2) cotton socks that retain moisture; (3) boots that are too tight or too loose; and (4) buckles cranked down too tight. Ensure proper sock fit, use merino wool socks, check boot fit, and avoid overtightening buckles. If feet are still cold, consider a midweight merino sock with medium cushioning rather than jumping to heavyweight.
