Ten Signs It is Time to Replace Your Everyday Work Shoes, Based on Science

Robert J. Snyder MD

When it comes to replacing your everyday working shoes, there are ten signs to consider, many which are based on published scientific data. See if you agree with these recommendations…

1. Worn-out soles: The soles of your shoes experience the most wear and tear. If the treads have significantly worn down, it’s time to replace them. A scientific study published in the Journal of Occupational and Environmental Hygiene suggests that worn-out soles can increase the risk of slips, trips, and falls.
2. Decreased cushioning: Over time, the cushioning in your shoes can break down, leading to reduced shock absorption. If you notice that your shoes no longer provide the same level of comfort or support as they did when they were new, it may be time for a replacement. A study in the Journal of Orthopaedic & Sports Physical Therapy found that worn-out cushioning can contribute to foot discomfort and impact on lower limb mechanics.
3. Pain or discomfort: If you experience pain or discomfort in your feet, ankles, knees, or hips while wearing your working shoes, it could be a sign that they no longer provide adequate support. Research published in the Journal of Foot and Ankle Research indicates that ill-fitting or worn-out shoes can contribute to foot pain and various musculoskeletal issues.
4. Visible damage: Inspect your shoes for any visible damage such as holes, tears, or separated seams. Damaged shoes may not provide the necessary protection and stability for your feet. A study in the Journal of Athletic Training suggests that structural integrity is crucial to reduce the risk of foot and ankle injuries.
5. Odor and hygiene issues: Persistent odor or difficulty in eliminating shoe odor can indicate the presence of bacteria and fungi. These microorganisms can contribute to foot infections and other health problems. A study in the Journal of the American Podiatric Medical Association highlights the importance of proper shoe hygiene to prevent foot infections.
6. Over 300-500 miles of usage: For running or athletic shoes, it’s generally recommended to replace them after 300-500 miles of usage, as stated by the American Academy of Podiatric Sports Medicine. While this guideline may not directly apply to all working shoes, it can still serve as a general reference for when to consider replacement.
7. Altered shoe shape: If your shoes have become misshapen, either due to wear or poor quality, they may not provide proper support and stability. A study in the Journal of Applied Biomechanics suggests that shoe design and shape affect foot and lower limb biomechanics, so alterations in shape can impact your gait and increase the risk of injuries.
8. Excessive pronation or supination: Pronation (inward rolling of the foot) or supination (outward rolling of the foot) beyond normal ranges can be indicative of improper shoe support or wear. If you notice an abnormal gait pattern, it may be time to consult a podiatrist or footwear expert to determine if your shoes need replacement.
9. Reduced traction: Traction is crucial for maintaining stability and preventing slips or falls, especially in workplaces with slippery or uneven surfaces. If you notice a significant decrease in traction on the outsoles, it may be time to invest in a new pair of shoes.
10. 10. Outdated technology or safety features: If your working shoes lack modern safety features or are based on outdated technology, it may be beneficial to upgrade to a newer pair that offers better protection and comfort. Stay informed about advancements in footwear technology, as new features can enhance your safety and overall well-being at work.

Remember that these signs should be considered as general guidelines. Depending on your specific work environment, occupation, and personal needs, you may need to replace your working shoes more frequently or take other factors into account.
