Sidi Sizing Information

Understanding Sidi-Specific Fits

Standard Fit: Designed for the average foot. It is sleek and narrow through the midfoot and heel.

Mega Fit: Sidi’s wide version. It is 4mm wider across the ball of the foot and offers more volume in the instep with a wider heel cup. If you usually buy wide sneakers, go with the Mega.

Women’s Specific Fit: Tapered more aggressively toward the toes with a narrower heel cup to help prevent slipping.

Key Notes for Boot Fitting

Narrow Fit: Sidi motorcycle boots are generally known for a narrower, European-style fit.

Measuring Your Foot: For the best result, measure from the back of your heel to the tip of your longest toe in centimeters.

Boots vs. Shoes: Heavy-duty racing boots like the Rex or Mag-1 may feel stiffer and tighter than casual riding shoes.
