Sizing Recommendations 

We recommend the inner sole of the Darcy boot to be around the same length as your foot. The neoprene lining around your foot will soften over time. 

The Darcy boot runs true to size. We suggest you go with your standard shoe size (don't order bigger for socks.) If you wear thick socks, then measure your foot wearing the thicker socks. 

If you are half size then size down, the boots should be slightly snug to start as the natural rubber will soften with wear.
