*The Nike / Adidas column is an approximate US men’s sneaker-size reference, not an official conversion chart from either brand. Fit varies by model and foot shape. Foot length means the length of your foot, not the shoe, insole, or centimetre size printed on a shoe label. Product-specific sizing guidance takes priority.

How to Measure Your Feet

  1. Wear the socks you intend to wear with your shoes.
  2. Place a sheet of paper on a firm, flat surface. Stand on it with your weight evenly distributed.
  3. Mark the back of your heel and the tip of your longest toe. Measure the distance between the marks in millimetres.
  4. Measure both feet and use the longer measurement as your starting reference.
  5. Compare your measurement with the chart. If it falls between sizes or near an overlapping range, contact us for advice about your selected style.

Choosing Your Size

Use US Men’s Sizing

This guide uses US men’s sizes as its main reference. Check the size options and fit information on the product page before choosing your size.

Know Your Brannock Measurement?

Your Brannock measurement is a useful starting point. Proper fitting considers heel-to-toe length, arch length, and width. The shape of the particular shoe can still affect the size that fits you best.

Comparing with Other Brands

Use your current shoe size as a comparison rather than a guaranteed match. For example, this chart lists US 8 alongside a US 9 sneaker reference. Different models may fit differently, so confirm with your foot measurement.

Width and Foot Shape

Standard D width is the medium-width reference used in this guide. Confirm the available width on the product page.

If you have wide or narrow feet, a high instep, or usually require a special width, contact us before ordering. Changing the length by half a size may not resolve a width-related fit issue.

Check the fit indoors: Try your footwear on a clean indoor surface. Your toes should not feel compressed, and your foot should feel comfortably supported. Keep the packaging while checking the fit and review our Return & Refund Policy if you need assistance.

The published chart above keeps its original units.

Use the foot-length range for this style. Measurements refer to your feet, not the outsole or insole.

Size and fit

Measure both feet and compare the larger measurement with the VALTVERO size guide. Open the zip fully when putting the boots on. Check the fit around your instep and ankle as well as the toe. For help, send us your foot measurements and this style before ordering.
