William is a great, tough looking Boys boot from Geox. There is a leather upper, Polyester fabric lining and a removable leather footbed. There are two adjustable velcro straps to keep the boots secure on the foot. There is a chunky rubber sole that is formed around the boot for added protection to the toes. These Geox boots also contain the unique Geox perforated sole unit that allows the shoes to breathe in that they allow the hot sweaty air inside the shoe to escape while stopping any moisture getting back onto the foot.
