Unfortunately, not all boot brands fit the same. For this reason, we would like to offer a few sizing tips that will help you get a better BELLEVILLE fit:
CHECK YOUR SIZE: Belleville boots are about 1 to 1½ full sizes larger in fit than your normal shoe size when measuring on a standard Brannock shoe device. The difference depends on the type of boot you choose: soft toe versus safety toe, hot weather versus insulated or waterproof, etc.
GET SOME BOOT SOCKS: Try on the boots with a pair of boot socks that you will normally wear with the boots.
PLACE & LACE: It is important that your foot is properly placed inside the boots when selecting a size. Proper foot placement requires that the lace is drawn snug at the bottom of the lacing system. This will prevent your foot from sliding forward too far and keep your heel properly placed against the back of the boot. To improve the fit of the boot, try loosening or tightening the laces at different parts of the boot until you get the perfect fit.
CHECK THE LENGTH: Length-wise, when your heel is placed against the back of the boot, you should have a slight amount of room in the front of the boots to wiggle your toes.
CHECK THE WIDTH: Width-wise, your boots should feel a little snug, but not tight.
TAKE A STROLL: Walk around to see how the boots feel. Make sure your heel stays in place and not sliding up and down (this can cause blisters).
Excellent!
