Boot and Skate Sizing Guide

When looking at skates, it is important to realize that sizing can differ significantly between brands and even between different models within the same brand. Because of this, we strongly recommend going through these steps before ordering a new skate or boot and that you revisit this guide once you have the skates to insure you have the right size and fit prior to skating on them.

Where to Start

To start the sizing process, you are going to want to know your true US Men’s and Women’s shoe size as well as an accurate measurement of the length of your foot.

To measure your foot, you will want to wear the weight of sock that you prefer to wear while skating. You will need a hard floor to stand on, pen or pencil, paper, and a ruler to complete these steps:

  • Get a piece of paper and put it up against the wall
  • Stand on the paper with your heel up against the wall and put weight on your foot as if you were standing normally
  • Mark the end of your longest toe on the paper
  • Step off of the paper and measure the end of the paper (heel) to the mark for your longest toe in BOTH millimeters (more accurate) and inches.

  • We recommend measuring both of your feet with this process to get the most accurate sizing recommendations.

Sizing Charts

Most brands will provide a sizing chart that will recommend a boot size based off of the length of your foot. These charts are very specific so you need to make sure that you are in the correct brand and that you are referring to the chart pertinent to the model you are interested in.

Sizing charts are found by clicking the “Sizing Chart” button on a product page or by visiting this page. These charts are provided by the manufacturers. For models that do not have a sizing chart, Derby Warehouse provides “Size Guidelines” in the description to help get you into the correct size.


It’s possible to get the correct size for your skate and not have them fit correctly. Have you ever tried on a pair of shoes that just wasn’t comfortable? Well not everyone’s foot is the same, maybe those shoes were too wide or they squished your toes together. It’s the same story with skates. Most skates are fairly neutral in their fit, but some people do have trouble with the way a skate feels. To help you, our staff tries on every one of our boots to provide you with ‘Fit Guidelines’ based on our experience. You will find this information in the product description as well.

Once Your Package Arrives

You have your new skates and want to try them out but WAIT! Before you eagerly jump out on the track or hit the road, put your skates on at home on a non-marking surface. Stand up, hop around on your toe stops and wiggle your toes. If you have any questions about how they feel, now is the time to ask us! If something feels strange to you, DO NOT USE YOUR SKATES!

Heat Molding

Some skates are heat moldable or have heat moldable counters. If you have your skates on and have a spot or two that are bothering you, this may be an easy fix through heat molding. If a skate is heat moldable, it will have a link to instructions in the description. You can also find instructions below. Heat molding is to fix mild to mildly moderate fit problems. If you are concerned whether heat molding will help, let us know before attempting to heat mold them; we would be glad to help you out!
