When to Buy New Shoes
Wearing the wrong or worn-out athletic shoes can lead to a host of injuries
including knee pain, ankle strain, and plantar fasciitis. Here are five key signs it's time to invest in a new pair.
1. Mileage Matters
Shoes typically last between 300 to 500 miles, depending on your weight and activity. For someone walking or running 15 miles a week, that means replacing shoes every 5 to 8 months. Tip: Write the purchase date on your calendar or inside the shoe.
2. Pain Is a Red Flag
If you're experiencing foot, leg, or knee pain, it’s likely your shoes are no longer providing the support your body needs.
3. Worn Treads = Worn Out
Like the tires on a car, once the treads wear down, your shoes lose traction and shock absorption, making injury more likely.
4. Your Feet Change Size
Yes — even as adults! Factors like pregnancy, aging, or weight changes can affect foot size. When buying athletic shoes, always go half a size up from your everyday shoes. Test the fit by sliding your foot to the front — if you can fit a thumb behind your heel, you’ve got the right size.
5. It’s Been 8–12 Months
Even if your shoes still look okay, the materials degrade over time, especially with exposure to weather or moisture. After 8 to 12 months, they likely don’t offer the structure and support they once did.
Final Tips:
Invest in high-quality athletic shoes ($100+).
Get professionally fitted to match your foot shape and arch.
Your shoes are your foundation — don't let worn soles lead to injury.
