Altra Running Shoes Size Guide: How to Find Your Perfect Fit

Finding the perfect fit in running shoes is essential for comfort, performance, and injury prevention. Altra running shoes are known for their unique foot-shaped design and zero-drop platform, making them popular among runners who prioritize natural foot movement and comfort. However, because of these distinctive features, selecting the right size can sometimes feel tricky. This guide will walk you through everything you need to know about choosing the perfect fit for your Altra running shoes.


1. Understanding Altra’s Unique Sizing Features

Altra running shoes stand out from conventional footwear primarily because of two design elements:

  • FootShape™ Toe Box: Unlike traditional running shoes that taper toward the toe, Altra’s FootShape™ toe box is wide and roomy, allowing toes to splay naturally.
  • Zero-Drop Platform: The heel and forefoot sit at the same level, promoting a natural running gait and posture.

These features impact how the shoes fit, so it’s important to consider them when selecting your size.


2. How Altra Sizing Differs From Other Brands

Altra shoes generally run true to size in terms of length, but the width and toe box shape might feel different if you’re used to narrower running shoes.

  • Length: Stick to your usual running shoe length or try half a size up if you prefer extra room.
  • Width: Due to the wide toe box, Altra shoes will feel roomier in the forefoot compared to many other brands. This can be a pleasant surprise for those with wider feet or toe splay but might require some getting used to.

3. Measuring Your Feet for Altra Shoes

To find the perfect Altra size, it’s best to measure your feet accurately:

  • Step 1: Place your foot on a piece of paper and trace the outline.
  • Step 2: Measure the length from heel to the longest toe.
  • Step 3: Measure the width at the widest part of your foot.
  • Step 4: Compare your measurements with Altra’s size chart, which includes width guidelines.

Keep in mind that feet can swell during running, so allow some extra space (about a thumb’s width) in the toe box.


4. Tips for Trying On Altra Running Shoes

When you try on Altra shoes, follow these tips to ensure the best fit:

  • Try on both shoes: Feet can differ in size; always fit to the larger foot.
  • Wear running socks: Test with the type of socks you plan to run in.
  • Check the toe box: Your toes should have enough room to wiggle and spread.
  • Heel fit: The heel should be snug without slipping.
  • Walk and jog: Take a few steps or jog in place to assess comfort and fit.

5. What to Do If You’re Between Sizes

If your measurements fall between two sizes:

  • Choose the larger size for more comfort and room.
  • Consider trying different models, as some Altra shoes have slightly different fits.
  • Remember that Altra shoes generally accommodate wider feet, so a half size up rarely feels too big.

6. Additional Factors to Consider

  • Orthotics: If you use custom insoles or orthotics, you might need to size up to accommodate them.
  • Foot shape: People with narrow feet may find Altra shoes roomier than expected.
  • Socks thickness: Thicker socks require slightly more room.

Conclusion

Altra running shoes offer a unique fit designed to enhance natural foot movement and comfort. To find your perfect size, measure your feet carefully, try shoes on with the right socks, and focus on both length and width. Don’t hesitate to size up if you’re between sizes or want extra toe room. With the right fit, your Altra shoes will help you run comfortably and efficiently, supporting every step of your journey.
