The Fumetsu shin guard range covers MMA, BJJ no-gi training and Muay Thai sparring. Each model uses S/M and L/XL sizing based on shin length and calf circumference. Use the chart below to match your measurements to the right size.
Fit tip: A shin guard should sit snug against the shin bone without rotating mid-kick. If you're between two sizes, the smaller size gives a tighter hold; the larger size leaves room for thicker training socks underneath.

How to measure
- Shin length: From the bottom of the knee cap to the top of the ankle joint.
- Calf circumference: Around the widest point of your calf in training shorts.
