KOI Footwear styles generally run true to size. KOI designs across UK and EU sizing, with a detailed size guide available to help you find the right fit.

KOI shoes are designed to run true to size. However, certain styles may fit slightly differently. Chunky boots with thicker linings may feel snug at first but tend to break in, while trainers and Mary Janes typically fit true from the start. If you have wider feet or are between sizes, sizing up is generally recommended. The KOI size guide provides specific measurements to help you choose with confidence.

• Boots: May feel snug initially, break in with wear. Size up if between sizes
• Trainers: Generally true to size
• Mary Janes: Generally true to size
• Wide feet: Consider sizing up

If you are between sizes, KOI recommends sizing up rather than down, particularly for boots. Platform boots with thicker linings benefit from the extra room, while trainers and Mary Janes tend to fit true to size. The best approach is to check the KOI size guide for the specific style you are considering, as fit can vary slightly between designs.

• Between sizes: Size up, especially for boots
• Boots: Size up for comfort with thicker socks or insoles
• Trainers and Mary Janes: Stay true to size

KOI boots, trainers and Mary Janes are all designed to run true to size, but each category has a slightly different fit profile. Chunky boots have a more structured fit with thicker linings, which may feel snug at first but break in over time. Trainers offer a more relaxed, flexible fit from the start. Mary Janes have a secure strap fit that holds the foot in place. Checking the size guide for your specific style is always recommended.

• Chunky boots: Structured fit, may feel snug initially, breaks in
• Trainers: Relaxed, flexible fit from the start
• Mary Janes: Secure strap fit, true to size

KOI does not currently offer a dedicated wide fit range. However, some styles are naturally more accommodating for wider feet due to their design.

• No dedicated wide fit range at present
• Rounded toe styles: Naturally more accommodating
• Recommendation: Size up if you have wider feet

The best way to choose the right size is to use the KOI size guide, which provides detailed measurements in UK and EU sizing.
