ALPINESTARS Stella SMX-1 R Black-Gold

Indicates who the motorcycle shoes or boots are designed for. The fit and sizing are adapted to the foot, providing more comfort and better control while riding.

• Men: Designed based on the male foot shape, typically with a slightly wider fit. Often also available in smaller sizes, making many models perfectly suitable for women or younger riders.
• Women: Specifically developed for the female foot, usually with a narrower heel and a more tailored fit. The range is sometimes more limited. If you do not find your ideal women’s model, feel free to check the men’s or unisex models as well. These are often available in smaller sizes and in many cases offer the same level of comfort and protection.
• Kids: Designed for children’s feet with adapted sizing and comfort. Note that older children (from around 12 years old) often already wear adult shoe sizes such as 38, 39 or larger. In such cases, smaller adult models can be a perfect alternative with the same level of protection and quality.

Tip: The women, men and kids categories are mainly a fit guideline. In practice, many unisex or men’s models also fit women or younger riders perfectly thanks to the wide size range available.

The waterproofing of motorcycle shoes and boots determines the level of protection against rain and moisture while riding. This is defined by the presence and type of membrane in the footwear.

• Gore-Tex waterproof: Premium shoes or boots with an advanced Gore-Tex membrane. Offer the highest level of waterproof protection combined with excellent breathability. Ideal for intensive use and long rides in wet conditions.
• Waterproof: Equipped with a waterproof membrane that keeps feet dry in rain and wet conditions. Provide reliable protection in changing weather, but without Gore-Tex-specific performance.
• Not waterproof: Without a membrane. These models are focused on ventilation and comfort in warm and dry weather, but offer no protection against rain.

The closure system of motorcycle shoes and boots determines how they are put on, secured, and adjusted around the foot and ankle. Some models combine multiple closure systems to optimize comfort, fit, and ease of use.

• ATOP rotor: Dial system with steel cable that allows quick and precise fit adjustment, even while wearing gloves.
• BOA rotor: Similar to ATOP, featuring a dial and cable system. Known for precise fit and even pressure distribution.
• Double zipper: Zipper on both sides of the boot, allowing it to open wider for easier entry. Mainly used on taller boots.
• Zipper: Practical closure that makes putting on and taking off easier. Often combined with laces or velcro.
• Velcro: Hook-and-loop closure providing extra fixation, often used together with a zipper or around the shaft.
• Laces: Traditional closure that allows precise fit adjustment. Often combined with a zipper for added convenience.
• Buckle: Adjustable buckle closure, mainly used on adventure and off-road boots. Provides secure and solid fastening.
• Quicklace laces: Fast-lace system that tightens the shoe in one motion. Practical and quick to use.
• None: Models without an active closure system. These rely on their fit, elasticity, or slip-on construction.

Gear shift reinforcement indicates whether the footwear features an additional protective panel in the gear-shift area, designed to prevent wear and damage caused by the gear lever. The available options are:

• Yes: the footwear is equipped with a reinforced panel at the point of contact with the gear lever. This increases durability and protects the material from premature wear.
• No: the footwear does not include a dedicated gear shift reinforcement. This may be sufficient for light use, but offers less protection against wear from gear shifting.

Ankle protection at ankle level provides added safety for a vulnerable part of the foot while riding. In touring boots, the focus is on achieving a good balance between protection, comfort and freedom of movement, especially during long rides.

The outer material of motorcycle shoes and boots largely determines protection, durability, and wearing comfort. Manufacturers use different materials or combinations thereof, depending on the intended use, style, and desired features of the model.

The membrane in motorcycle boots, shoes, or sneakers is a waterproof and windproof inner layer that allows perspiration to escape. This keeps the feet dry and comfortable even in wet conditions. Not all models are equipped with a membrane; some shoes and sneakers do not have this feature. There are various brands and membrane technologies, each with their own characteristics and level of protection.

The lining of motorcycle shoes, boots, or sneakers affects comfort, breathability, and moisture management inside the footwear. The most commonly used materials are:

• Polyester: lightweight, soft, and comfortable material that wicks moisture well and dries quickly. Polyester is durable and easy to maintain.
• Polyamide: strong, durable, and breathable material that effectively transports moisture and provides a comfortable interior.
