At Cru Nonpareil, we make shoes in different shapes to fit people's feet. The shape of the shoes can affect how they fits and look. Our shoes generally fit true to size, but the width of the front of the shoes can vary. Our sizes are based on the US standard, with medium width similar to UK E width. 

If you usually wear a US size 9, you should expect a size 9 in our shoes to fit you. However, different styles of shoes, like loafers or oxfords, may fit differently. Loafers may feel looser because of the way they are made. Suede shoes may also feel more generous than leather ones. If you like your oxfords to fit snugly, you may want to go up a half-size for boots. But for most people, the same size as their oxfords should work.
