FAQs
Are these shoes suitable for outdoor basketball courts?
While the Air Jordan 40 offers robust traction, its design and premium materials, particularly the suede upper, are optimized for indoor court performance. Frequent use on rough outdoor surfaces may accelerate wear and tear on the outsole and upper.
How do I clean the suede upper without damaging it?
Gently brush off loose dirt with a suede brush. For tougher spots or stains, use a dedicated suede cleaner applied with a clean cloth. Always blot, do not rub aggressively, and allow to air dry completely before re-brushing.
What is the benefit of `ZoomX` foam and `Zoom Strobel` cushioning?
This combination provides an incredibly responsive and energy-returning feel. `ZoomX` offers superior cushioning and bounce, while the full-length `Zoom Strobel` brings this cushioning closer to your foot, enhancing explosiveness and court feel during dynamic movements.
How should these shoes fit?
They should fit snugly and securely, especially around the midfoot and heel, to provide optimal lockdown. Your toes should have a small amount of room to move, but your foot should not slide forward or side-to-side during quick movements.
Is a break-in period necessary for the Air Jordan 40?
Yes, due to the advanced containment features and robust cushioning, a short break-in period of a few light wears is recommended. This allows the materials to mold to your foot for maximum comfort and performance.
Can I use these shoes for general casual wear?
While stylish, the Air Jordan 40 is engineered as a high-performance basketball shoe. Wearing them primarily for casual purposes will not harm them, but their full performance benefits are realized on the court. Casual wear may also expose the suede to elements not ideal for its upkeep.
How do the internal webbing straps enhance performance?
The six internal webbing straps integrate with the lacing system to pull the upper material tightly around your foot. This creates a secure, custom fit that prevents internal foot movement, offering superior stability and containment during aggressive cuts and landings.
Troubleshooting
Traction feels inconsistent or slippery.
Clean the outsole thoroughly to remove any dust, dirt, or debris that might be impacting grip. Ensure the court surface is also clean. If the issue persists, inspect the herringbone pattern for excessive wear.
Foot feels loose or not fully contained during play.
Re-lace the shoes, ensuring that the laces are pulled tight through all eyelets, especially around the ankle collar. Utilize the internal webbing straps by adjusting the lacing to provide a secure, locked-down fit. Consider wearing thicker athletic socks for a snugger feel.
Discomfort or rubbing during initial wears.
The shoes may require a break-in period. Wear them for shorter, less intense sessions to allow the materials and cushioning to adapt to your foot. Ensure you are wearing appropriate athletic socks. If discomfort persists, check sizing or lacing technique.
Suede upper appears dull or stained.
Use a specialized suede brush to restore the nap and remove surface dirt. For stains, use a high-quality suede cleaner according to its instructions. Always test cleaners on an inconspicuous area first.
Squeaking sound from the sole.
A common occurrence in new performance shoes, this often subsides with wear. Ensure laces are tied securely. If persistent, clean the outsole as dirt can sometimes contribute to squeaking. > Info needed: Specific squeaking troubleshooting steps if it indicates a defect.

Setup, Compatibility & Care
Initial Setup
Lacing: Ensure laces are threaded evenly through all eyelets. Start from the toe and work your way up.
Fit Adjustment: Lace the shoes snugly, but not overly tight. You should be able to wiggle your toes slightly, and your heel should feel secure without lifting excessively.
Break-In (Recommended): Wear the shoes for a few light sessions before intense play to allow them to conform to your foot's shape and for the cushioning to fully activate. This can help prevent discomfort during initial heavy use.
Compatibility
Sport: Primarily designed for basketball and other indoor court sports requiring dynamic movements and high impact absorption.
Surfaces: Best suited for indoor court surfaces (e.g., hardwood, synthetic gym floors) to maximize traction and preserve the outsole.
Wear: Ideal for competitive play and training sessions where performance is paramount.
Care Instructions
Cleaning the Upper (Suede):
Brush off loose dirt with a soft-bristled brush (a dedicated suede brush is ideal).
For stains, use a suede cleaner specifically designed for the material. Apply sparingly to a clean cloth and gently blot the stained area. Avoid excessive rubbing.
Allow to air dry completely away from direct heat or sunlight.
Brush the suede lightly again to restore the nap.
Cleaning the Midsole/Outsole: Wipe with a damp cloth and mild soap to remove dirt and grime. For stubborn dirt in the traction pattern, use a soft brush.
Drying: Always air dry your shoes at room temperature. Avoid machine dryers, as high heat can damage materials and adhesives.
Storage: Store in a cool, dry place away from direct sunlight. Consider using shoe trees to help maintain their shape.
Avoid: Do not machine wash or submerge in water. Avoid harsh chemicals or abrasive cleaners that can damage the suede or other materials.
