2. Lacing and Fitting
- Insert Sock Liner: Ensure the removable MEMORYfōm sock liner is correctly placed inside each shoe.
- Lace Adjustment: Loosen the laces sufficiently to allow your foot to slide in comfortably.
- Foot Placement: Insert your foot, ensuring your heel is seated firmly against the back of the shoe.
- Tighten Laces: Gradually tighten the laces from the toe upwards, ensuring a snug but not overly tight fit. There should be enough room to wiggle your toes slightly.
- Test Fit: Walk a few steps to assess comfort and fit. Adjust laces as needed.

Operation
The Avia Avi-Union II shoes are designed for demanding work environments, offering comfort and safety features for individuals who spend extended periods on their feet.
1. Intended Use
These shoes are ideal for professions requiring slip-resistant footwear, such as food service, healthcare, and other industries where wet or oily surfaces are common. They are engineered for all-day comfort and support.
2. Key Features and Benefits
- Non-Slip Outsole: The thick rubber sole features an oil and slip-resistant tread pattern, certified ASTM F2913, designed to enhance grip and prevent liquid trapping. This ensures stability on various surfaces.
- Memory Foam Comfort: The removable MEMORYfōm sock liner provides personalized pressure point relief, conforming to the unique contours of your foot for enhanced comfort during long shifts.
- Supportive Design: Featuring a compression-molded EVA midsole, anatomical heel cradle, and Avia's Cantilever Technology, these shoes center and stabilize the heel, offering exceptional shock absorption and cushioning.
- Water and Stain Resistance: The synthetic leather upper is treated with Defender by Scotchgard, providing resistance against water and stains to keep your feet dry and protected from spills.

Maintenance
Proper care will extend the life and maintain the performance of your Avia Avi-Union II shoes.
1. Cleaning Instructions
- Exterior: Wipe the synthetic leather upper with a damp cloth to remove dirt and spills. For stubborn stains, use a mild soap solution and a soft brush, then wipe clean.
- Soles: Clean the outsoles regularly to remove debris that could compromise slip resistance. Use a brush and water to scrub the tread pattern.
- Laces: Laces can be removed and hand-washed with mild soap and water if necessary.
- Do Not Machine Wash: Machine washing is not recommended as it can damage the shoe's structure and materials.
2. Care for Memory Foam Sock Liners
The removable MEMORYfōm sock liners can be taken out for airing. If they become soiled, hand wash them gently with mild soap and water, then allow them to air dry completely before reinserting into the shoes.
3. Storage
Store your shoes in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing them in damp environments to prevent odor and material degradation.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Discomfort or Pressure Points | Incorrect lacing, improper size, or new shoe break-in period. | Ensure laces are not too tight or too loose. Verify shoe size using the provided size guide. Allow a short break-in period for the shoes and memory foam to adapt to your feet. Consider trying different socks. |
| Reduced Slip Resistance | Accumulation of dirt, oil, or debris in the sole tread. | Regularly clean the outsoles with a brush and water to remove any trapped substances. Ensure the tread pattern is clear. |
| Odor Development | Moisture buildup inside the shoe. | Remove and air out the memory foam sock liners after each use. Ensure shoes dry completely if they become wet. Consider using shoe deodorizers. |
| Sole Separation | Normal wear and tear over time, or exposure to harsh conditions. | While designed for durability, all footwear has a lifespan. Ensure proper maintenance and avoid excessive exposure to chemicals or extreme heat. If separation occurs prematurely, refer to warranty information. |
