Do you find yourself frustrated while trying to adjust your fin Straps while floating in the water or while wearing bulky diving gloves? Have you ever discovered that your fin strap was too tight or too loose too late? The spring heel straps offer ditching/donning ease and dive long comfort. You'll never battle fin straps again after installing a pair of Spring Heel Straps. Scubapro's Spring Heel Straps are designed for the Jet Fins (see SKU: SCPFJ) and are sold in pairs. These corrosion resistant straps have a comfortable cover and steel springs that are depth compensating so they will contract when you go to depth and your boots compress with the increase of water pressure. They will also re-expand upon ascent. Straps are available in multiple sizes.
