The correct size is one of the most important things to consider when purchasing cowboy boots and any other types of shoes. Therefore, check the shape of the toes, the length of the footwear, the heel height, and the width of the calf. For length, measure from the longest points of your foot. Meanwhile, to determine your calf width, measure around the widest part of your calf. To get an accurate measurement, grab a piece of paper and draw around your foot. The figures can then be compared to the sizing chart of the manufacturer.
