Street 3 Lady Air are certified motorcycle shoes created to offer the perfect combination of protection on the saddle and freedom to walk in everyday situations. The mesh fabric upper ensures optimal ventilation even in the hottest climates. They are designed according to the Woman Fitting Concept, the special TCX protocol designed to combine perfect fit for the female foot with maximum safety.
Protection is guaranteed by toe and heel reinforcements and D3O inserts on the ankle. This patented material is soft and flexible, but designed to stiffen in the event of an impact.
One of the key points that produce a perfect balance of protection and comfort on the Street 3 Lady Air shoe is the highly resistant yet flexible sole, characterized by the special molded polymer Zplate� insert, which combines transversal rigidity for maximum safety and longitudinal flexibility precisely due to its Z shape. Zplate� allows the shoe to follow all natural movements of the foot both in the saddle and when walking, but protects at the same time and prevents the shoe from being crushed in an impact.
The Ortholite� insole is optimized to offer the sole of the foot long-lasting cushioning even after many uses and better breathability in all conditions. The Groundtrax� sole features self-cleaning tread and compound specifically designed to resist wear and adhere better to the controls on the bike. They are fastened using laces, with a concealed system that adopts an elastic eyelet on the tongue.

How to Measure the Feet
| Step | Instructions |
|---|---|
| 1. Measure Both Feet | Measure both feet at the end of the day while wearing the socks you plan to use. |
| 2. Stand on Paper | Place the heel against a wall and mark the tip of the longest toe. |
| 3. Use the Longer Foot | Compare both measurements and use the longer foot for selecting the size. |
| 4. Check the Chart | Compare the measured foot length with the TCX chart. |
| 5. Check the Fit | The shoe or boot should feel secure without painfully compressing the toes or instep. |
Fit: Motorcycle shoes and boots should hold the heel and midfoot securely while leaving enough room for the toes. Racing and off-road models may feel firmer than urban or touring footwear because of their protective construction.
Not every size is available for every TCX model. Selected women's models use the TCX Woman Fitting Concept with a female-specific fit.
