Is Your Boot Size The Same As Your Shoe Size?

Why do boot size and shoe size differ so much?

A variety of factors contribute to the variation in boots and shoe sizes and they include the following:

  1. Shoe last

Sizing inconsistencies usually begins at the factory where the shoes are made. When shoes or boots are being designed, the fit is established by a tool known as a shoe last. Shoe lasts are sculpted, toeless prototypes of the feet. They come in a range of sizes and shapes. A different last is required for each distinct shoe size that a manufacturer makes.

Since shoe lasts comprise a central part of a manufacturer’s protected design, shoe manufacturers would be at a disadvantage if they utilize a standardized industry last. This is why shoe brands do not have identical size shoes. Therefore, if you purchase shoes from one manufacturer of a specific size, you almost certainly have to choose a different boot size if you are purchasing from another brand.

  1. Measurement type used

Boot or shoe sizes are determined using different methods. For instance, British and American shoe sizes are determined using the shoe’s last length, and this is measured in barleycorns. The barleycorn is a very old English unit for measuring length. It equals a third of an inch. A shoe size is ascertained by using the following formula:

Men’s shoe size = 3 x (Last Length) – 25

Women’s shoe size = 3 x (Last Length) – 23

UK sizes are US size – For example, a UK size 10 is a US size 11.

By and large, the foot length would be 2 barleycorns shorter compared to the shoe’s last length. Some boot manufacturers and shoe brands employ a size that tallies with Brannock device measurements. Brannock device measurements are also connected with the UK/US shoe sizing systems but are based upon the foot size. Generally, a Brannock size is approximately a half-size shorter (approximately 2 barleycorns) compared to the traditional sizing system.

Knowing all these is important because a boot manufacturer might employ conventional sizing, or they may employ Brannock sizing. When they use Brannock sizing, the boots or shoes you are considering will tally with your foot size. But if they employ conventional sizing, the shoes or boots will be somewhat larger than your foot.

  1. Boot construction method

Boots are constructed using various techniques and the common ones are Goodyear welted construction, stitchdown construction, and Blake construction.

Boot construction method

Goodyear welted construction: In this method, a canvas rib is first attached to the boot’s insole using glue. This setup is then sewn to a leather piece (the welt). Lastly, the welt is sewn to the boot’s outsole and midsole.

Stitchdown construction: In this technique, the leather used in making the upper is pulled out above the midsole. This is then attached to the outsole and midsole using what is referred to as a rapid stitch.

Blake construction: This technique involves directly stitching the boot’s upper and insole to the outsole. This technique is commonly utilized for dress shoes.

The various construction and stitching methods typically give rise to variations in boot sizes. For instance, a size 8.5 Goodyear welted boot may be more like a 9 if a comparable boot is constructed using the stitchdown construction technique.
