REX AIR - Boots - Black - UK 8

While designed for maximum protection on the street and worn by pro riders, they are primarily intended for street use. For dedicated track racing, specific track-focused boots might offer additional features.

Refer to the Sidi sizing chart and measure your foot length. The UK size 8 listed is a specific option; ensure you select the size that best matches your measurements for a secure fit.

EN 13634 is a European standard that specifies the requirements and testing methods for motorcycle protective footwear, ensuring a minimum level of protection.

Individual components like the dial and cables are often replaceable. For significant damage, contact Sidi customer support or a certified dealer for repair options.

The REX AIR model features a perforated upper for breathability, which means they are not waterproof. They are designed for ventilation, not protection against water ingress.

Warranty details can vary by region and retailer. It is recommended to check the warranty information provided at the time of purchase or contact Sidi customer service for specific details.

Ensure the mechanism is clear of debris. A small amount of silicone-based lubricant can be applied to the cable and mechanism if necessary, following manufacturer guidelines.

The boots may require a break-in period. Wear them for shorter durations initially and gradually increase wear time. The Tecno-3 system allows for micro-adjustments to relieve pressure.

Ensure the air vents are not blocked by debris or dirt. Check that the perforated areas of the upper are clean.

These components are designed to be replaceable. Refer to Sidi's official parts and service information for replacements.
