How Vionic Shoes Fit
Vionic shoes generally run true to size. However, due to their structured footbeds and unique arch support, some customers may find a slight adjustment period when switching from traditional flat insoles.
Here’s what to keep in mind:
- Fit may feel snug at first: The built-in orthotic support can make the shoe feel different, especially around the arch and heel.
- Half sizes are available in most styles: This helps fine-tune the fit, especially for closed-toe shoes.
- Widths vary by style: Many Vionic shoes are offered in medium (B for women / D for men) and wide (D for women / E or EE for men) widths.
- Adjustable options: Many sandals and flats feature straps or buckles, helping to customize the fit for high insteps or narrow feet.
Sizing Tips by Footwear Type
Different types of Vionic shoes may fit differently depending on materials, structure, and flexibility. Here’s how to approach sizing based on the type of shoe:
- Sandals: Generally true to size. Look for models with adjustable straps if you’re between sizes.
- Sneakers: Fit true to size, but opt for a half size up if you plan to wear thick socks.
- Dress shoes: Can fit more snugly—consider sizing up a half size if you’re between sizes.
- Slippers: Often have a relaxed fit. Stick with your usual size unless you prefer a very secure fit.
Measuring Your Feet at Home
Before ordering, it’s a good idea to measure your feet—especially if it’s been a while. Use a printable foot measuring chart or follow these steps:
- Place a piece of paper on a flat surface and stand on it.
- Mark the longest point of your foot (toe to heel).
- Measure in inches or centimeters.
- Repeat for the other foot and use the longer measurement.
- Compare your foot length to the Vionic sizing chart.
