The Sidi Blade Boots are the lightest boots in the Sidi line. With a Lorica outer construction, and perforated, Teflon treated nylon lining, these boots are going to provide airflow and won't give you that 'weighted' feeling. The interior of the boots have a composite inner sole, and removable arch support. There is a fully encapsulated heel cup for safety, and the high-stress areas have been double stitched. Sidi has also incorporated a DuPont polymer toe shift pad, and a replaceable nylon toe scuff pad. For increased visibility, there is a reflective panel on the heel.

Finding your foot measurements:Trace around the foot, while standing with the feet flat on the floor.
Do this for both feet, as you will use the largest of the two measurements to find your size.
Mark the outer edges, and the top and bottom points of your tracing.
Measure from the top to the bottom to get your size measurement, and from side to side to get the width.
