How are Muck Boots sized?
Muck Boots are available in whole sizes (with the exception of the Wellie Classic and Woodland's series). Muck Boots are more flexible and forgiving than stiffer boot brands, so finding the correct size is easy: just base your choice on your athletic footwear size. Please check the size label inside your most recent pair of athletic shoes prior to ordering or purchasing a pair of Muck Boots.

For boots: Order based on your athletic shoe size. If you wear a half-size, go down to the next whole size in boots only. For example: A men's 9.5 would order a size 9 boot. A women's 9.5 would order a size 9 boot.

For shoes, order based on your athletic shoe size. If you wear a half-size athletic shoe, men move up to the next whole size while women move down to the next whole size. For example: A men's 9.5 would order a size 10 shoe. A women's 9.5 would order a size 9 shoe.

How can I tell if my Muck Boots fit?
When footwear fits properly, you should be able to wiggle your toes freely inside the boot, and your heel should have minimal lateral movement. For those with particularly narrow heel widths, try socks with extra heel cushioning, or a short, heel-only insole to tighten the fit around the heel area.

What kind of socks do I wear with my Muck Boots?
Medium-weight athletic socks are fine for most Muck Boot styles. Since Muck Boots use a flexible neoprene inner, you generally don't need the kind of thick, cushioning socks that are obligatory with other brands' super-rigid (and less insulated) boots. Another advantage of the neoprene inners is that they stretch, which means you can wear your boots with different thicknesses of socks, depending on your activity level and the season. For use with heavy socks, true half sizes should select the next size up.

Do Muck Boots accommodate different widths?
Yes. Muck Boots are made to standard widths but the materials will stretch comfortably to fit widths up to EEE. For narrow feet, we suggest wearing a thicker sock or putting a standard drugstore insole to take up room. Often, this is enough to help you achieve a more perfect fit.

Can I use insoles?
Yes. The insole liner in Muck Boots is fully removable; if you choose to use an extra insole or liner in your boots, pull out the Muck Boot insole, add your extra liner and then replace the original insole. This way the extra liner is held firmly in place, with less sliding. Muck Boots can also accommodate special orthotic insoles from your podiatrist.

Do Muck Boots accommodate different calf sizes?
The topline (or open collar) and upper calf area of all Muck Boots is constructed of soft, comfortable CR-foam which stretches to accommodate virtually all calf sizes. The flexible upper also allows for the pant leg to be worn over or inside the boot. In warmer conditions, the upper can be folded down to allow hands-free removal and improve air circulation.
