The Ion Plasma shoes fit great and provide protection from the elements. The segmented sole has strategic gaps in the rubber to provide added flexibility where you need it most, the slim fit means they will work when windsurfing with footstraps. These shoes come up over the ankle just a bit, so they stay on well and keep the sand out. There is also a pull string/draw cord at the top to cinch them up snungly. These are a great water shoe for entry level windsurfers who want a great value in a water shoe that will stay on well and protect your feet from shells and rocks.
