Fergie Tall Rain Boot

Stand with your weight evenly distributed across both feet. Place a ruler or measuring tape against a wall and measure from the back of your heel to the tip of your longest toe (this isn't always your big toe). Measure both feet and use the longer measurement when choosing your size. If you usually wear thick socks with your boots, measure with the socks on.

Use the inner sole length column in the measurement chart above. Match your foot length to the inner sole length for the size you're considering. Your foot should be the same length as the inner sole, or up to about 1 cm shorter, so the inner sole is the same length as your foot or very slightly longer. Fergie inner soles run from 23 cm (EU 36) to 28.7 cm (EU 43).

Yes, our boots fit true to size. If you're a half size, don't guess based on your usual shoe size. Measure your foot and choose the size where the inner sole is 0.5 to 1 cm longer than your foot. The inner sole length for each size is in the measurement chart above.

For foot width, measure across the widest part of your foot (around the ball of the foot or bunion joints), then compare to the inner sole width on the size chart. Our Fergie boots are a standard B width.

Because Fergie is a knee-high boot, you can also check the calf width column in the measurement chart above. Measure around the fullest part of your calf and compare. Fergie also has an adjustable gusset at the back to help accommodate a range of calf sizes.

Neither by default. Measure your foot first. The right size is the one where the inner sole is 0.5 to 1 cm longer than your foot (use the inner sole length column in the measurement chart above). The neoprene lining will soften and mould to your feet over time like memory foam, so a slightly snug start is normal.

Go with the size that fits your larger foot. If the difference is significant, you can remove the innersole on the larger side for up to half a size extra room, or add an orthotic to the smaller side for a snugger fit.
