Size Guide
Whether you already know your size or need help figuring it out, this guide will help you confidently choose the right fit for our Carrara sneaker. With just a few quick measurements, you'll be able to determine the Koio size that works best for your feet and your comfort preferences.
Instructions to Measure Your Foot
Follow these simple steps to get an accurate measurement:
- Place a sheet of paper against a wall or straight edge.
- Stand with one foot on the paper, heel touching the wall.
- Using a ruler, measure from the wall to the tip of your longest toe.
- Record the measurement in centimeters or inches.
- Repeat the process with your other foot.
- Compare your measurement to our size chart below.
- The centimeter (CM) and inch (IN) measurements in the size guide represent the maximum foot length that comfortably fits each size. For the best fit, we recommend selecting a size where your foot length is slightly less than or equal to the listed measurement — depending on your personal comfort preference and how much room you like in your shoes.
- For example: If your foot at the longest toe measures 29.5 cm, that falls between 29.0 cm (US 11) and 29.8 cm (US 12)—in this case, your size is a US 12.
