When it comes to managing plantar fasciitis, the right shoes are just as crucial as the right size. Shoes designed for plantar fasciitis offer specialized support, but if they don’t fit properly, even the best features won’t help relieve your pain. From arch alignment to heel support, getting the correct size ensures your footwear actually aids in healing rather than making your condition worse. Here’s your comprehensive guide to finding the perfect fit for plantar fasciitis shoes.
Why Proper Fit Matters for Plantar Fasciitis
The wrong shoe size can amplify pressure on your heel, strain your arch, and throw off your gait—leading to worsened inflammation of the plantar fascia. A perfect fit supports your foot’s natural shape, reduces pressure points, and keeps your heel properly aligned within the shoe’s cushioning and support system.
1. Know Your Foot Type
Before choosing a size, understand your foot shape and biomechanics.
Check for:
- Flat feet – Often need more arch support.
- High arches – Benefit from extra cushioning under the arch and forefoot.
- Overpronation – A common issue in plantar fasciitis, where the foot rolls inward.
Knowing your arch type helps determine the kind of support you need and may influence how a shoe fits length- and width-wise.
2. Measure Your Feet Properly
Feet change over time due to weight changes, aging, pregnancy, or activity level. It’s crucial to measure both feet before buying new plantar fasciitis shoes.
How to measure:
- Stand while measuring for the most accurate length and width.
- Measure both feet—go with the larger foot’s size.
- Measure at the end of the day when your feet are slightly swollen (this mimics a realistic shoe fit).
Use a brannock device or printable sizing chart from the brand you’re considering.
3. Consider Width Options
Plantar fasciitis shoes often come in multiple widths—narrow, medium, wide, or extra wide. A shoe that’s too tight can compress the arch and aggravate the heel, while a shoe that’s too loose can reduce support and cause slippage.
Pro Tip: Brands like Orthofeet, New Balance, and Brooks offer a broad range of widths, which is ideal for both wide-footed and narrow-footed shoppers.
4. Check the Heel Fit
A snug but not tight heel is essential. The heel cup should:
- Hold your heel securely in place
- Prevent slipping
- Align your heel with the cushioning system for optimal shock absorption
Avoid shoes where your heel lifts with each step or feels squished.
5. Pay Attention to Toe Box Room
The toe box should be roomy enough to let your toes spread naturally but not so loose that your foot slides forward.
Look for:
- Enough wiggle room for toes
- No pinching or rubbing at the sides
- Space between the longest toe and shoe front (about a thumb’s width)
6. Try Insoles with the Shoe
Many plantar fasciitis shoes come with removable insoles. If you plan to use custom orthotics or third-party insoles (like Superfeet or Powerstep), make sure:
- The shoe has enough depth
- The size accommodates the insole without making the shoe tight
Always try shoes with your insoles in place before committing to a size.
7. Account for Swelling and Sock Thickness
If you’re buying walking or running shoes, remember that your feet may swell during activity. Also consider the socks you’ll wear—thicker socks may require half a size up.
Tip: Try shoes on with the socks you plan to wear most often for a realistic fit.
8. Follow Brand-Specific Size Charts
Sizing can vary dramatically between brands (and even between models). Always consult the brand’s sizing guide and customer reviews before purchasing, especially if you’re ordering online.
Look for:
- Reviews that mention fit (runs small/large)
- Return policies for exchanges
- Brand-specific sizing tips (some brands recommend sizing up for orthotic comfort)
Final Thoughts
The best plantar fasciitis shoes combine proper support, cushioning, and fit—but even the most advanced pair won’t work if the size is wrong. Measuring your foot, understanding your biomechanics, and trying shoes on under realistic conditions are all essential steps to ensure pain relief and support. When in doubt, consult with a podiatrist or visit a specialty footwear store for a professional fitting.
Remember: The right size can mean the difference between daily discomfort and long-lasting relief. Give your feet the fit they deserve.
