Tabi Shoes Ninja Low Top Comfort-Cushioned ! Black Rikio Jikatabi Description How do you choose the right size? Easy Answer: Measure your foot in centimeters and add 0.5cm to it and that is your size. (exp. 23.5cm + 0.5cm= 24.0cm) Detailed Answer: The first thing you want to do is measure your foot. Take out a ruler and measure it in centimeters. Then check the length against the sizes we offer. Don't order one that matches your foot length, but instead order the next possible size. For example: If your foot measures exactly 24cm, then you should order 24.5cm. Or if your foot measures 26.5 cm, you should move up to 27cm. This is to ensure that they do not fit too tight. But what if your foot measures 27cm? Since the next size up is 28cm, is it really best to move up 1 whole centimeter? Well, our recommendation is yes, but you may find that your shoes fit a little big. We believe that a little big is better than a little too tight. It really depends on the individual foot, and each customer should choose a size they think will fit them best. And what if my foot measures 26.8cm or 26.9cm? Should I just order a size 27? Well since the size is too close to your measurements, it is probably best to move up to the next size, a size 28. Even though it may fit a little loose, a little loose is better than a little tight. And also the sides have clips which you can use to give them a tighter feeling around the leg. But remember, this is only our recommendation, and all people have different kinds of feet. There's no guarantee that shoes will always fit the way we hope. Features: Product Details: Department ‏ : ‎ mens Date First Available ‏ : ‎ April 23, 2014 Manufacturer ‏ : ‎ Rikio
