Motocross Socks: Knee-High MX Boot Socks for Riders
Motocross socks are the long, knee-high socks worn inside MX boots to prevent chafing, absorb sweat and keep the boot liner clean and comfortable. In this category, Foxracing.si brings together Fox motocross socks for riders of every level, from thin summer pairs for hot race days to thicker, padded models for enduro rides and long practice sessions, in adult and youth sizes.
What this category covers
- Knee-high MX socks – the classic motocross length that reaches over the calf, so the boot shaft never touches bare skin.
- Thin, moisture-wicking socks – light knits that move sweat away from the foot and keep the boot from turning slippery in summer heat.
- Thicker padded socks – extra cushioning at the shin, instep and heel for trail riding, enduro loops and boots that feel slightly roomy.
- Youth sizes – shorter, narrower cuts so young riders get the same protection without bunching fabric inside the boot.
- Socks for use with knee braces – smooth, flat-knit models that sit under a brace or knee guard without creating pressure points.
How to choose motocross socks
- Length: the sock must end above the top of the boot. Anything shorter leaves a gap where the plastic shaft rubs the calf and creates blisters.
- Size: follow your shoe size and choose a snug fit. A sock that is too big wrinkles under the foot; too small and the toe seam presses on your toes.
- Material: synthetic or blended knits with moisture-wicking fibres dry much faster than pure cotton, which stays wet and causes friction.
- Thickness: thicker socks add cushioning and fill out a slightly loose boot, while thin socks are better if your boots already fit tight or you ride in high temperatures.
- Seams and cuff: look for flat toe seams and a cuff that grips without cutting in, so the sock stays up through a full moto.
- Season: keep a thin pair for summer and a warmer, denser pair for cold-weather and winter riding, plus spares in your gear bag.
Brands
All socks in this category are made by Fox, a brand built around motocross riding gear, so the cut, length and knit are designed for use with MX boots rather than everyday shoes.
Frequently asked questions
Why do motocross socks need to be so long?
Because MX boots have a tall, stiff shaft. A knee-high sock covers the whole area the boot touches, preventing rubbing, hot spots and blisters on the calf and shin.
Can I just wear normal sports socks in MX boots?
Short sports socks leave your calf exposed to the boot shaft and buckles, and cotton socks hold sweat. Dedicated motocross socks are longer, thinner where the boot is tight and made from faster-drying yarns.
Do socks go over or under knee braces?
Most riders pull the sock up first and fit the brace or knee guard over it, so the fabric protects the skin from the brace hinges and straps.
What size motocross socks should I buy?
Choose the size that matches your normal shoe size. If you are between sizes and wear thick socks with roomy boots, the larger size is usually the safer choice.
How should I care for them?
Wash them after every ride at a low temperature and let them air dry. Avoid high heat and fabric softener, which can damage elastic fibres and reduce the grip of the cuff.
