Between Sizes?
If you’re between sizes, measure your larger foot and compare it to the chart. Then review the product description for style-specific fit notes, since toe shape, straps, and materials may affect fit.
MEASURING FOOT LENGTH
To measure your foot length, sit down on a chair and place foot flat on a piece of paper. Trace the foot by holding a pencil vertically and outlining the foot.
The longest toe and back of heel are the most important measurements. Using a ruler, measure the distance from the bottom of the heel to the tip of the longest toe.
Record the result in both inches and centimeters and use these measurements to find your size in the chart.
If one foot is larger than the other, the measurements for the larger foot should be used.
MEASURING HEEL HEIGHT
To measure heel height, measure from where the heel meets the sole to the bottom most tip.
Flat/Low: < 1”
Mid: 1” – 2.5”
High: 2.5” – 4”
Stiletto: > 4”
MEASURING CALF CIRCUMFERENCE
To measure calf circumference, wrap a soft measuring tape around the fullest part of the calf.
Standard Calf Circumference: < 16”
Extended Wide Calf: > 16”
MEASURING BOOT SHAFT HEIGHT
To measure boot shaft height, use a soft measuring tape to measure from the bottom of the foot up the length of the calf.
Ankle: 3” – 8”
Mid-Calf: 8” – 13.5”
Tall/Knee High: 13.5” – 17”
Over the Knee: > 17”
