The GoBioMed cast sock is a must-have for anyone with a broken or injured foot. Our cast covers are made from a sturdy polar fleece that can withstand significant use while providing comfort and breathability while being worn, protecting your toes from the elements. It has a bottom coated with tacky rubber to provide traction on a variety of floor surfaces and reduce the risk of becoming unsteady and falling. Our design features an adjustable nylon strap on the back to fit any size cast, as well as elasticized openings at the top to allow easy access to your feet. The cover is one size fits most due to its give and stretchiness.
