The exclusive 'Parabolic pressure control system' is a system of differentiated reinforcements which allows the blade to bend in the polymer according to a parabolic arc, to adapt to different intensities of finning. The ONE blade is extremely reactive due to the shape of biconcave that acts as a spring. The special tail profile maintains a stable shovel, without the typical 'derapage' of plastic fins, while the unique plug-in shoes, allows perfect energy transmission for smooth kicking. The holes in the initial part, reduce fatigue without losing thrust useful. Available in two different materials: black for temperate and warm waters, green for cold and temperate waters. The new DELTA-ONE shoe pocket is made with an innovative system that combines the use of thermoset rubber and fabric in a special composition in layers. careful studies have led to obtain a product of exceptional comfort combined with a perfect resistance to deformation even when the shoe is subjected to severe stress. The angle between the shoe and the blade is 22 ° for a perfect thrust power.","brand":"My Store","offers":[{"title":"Default Title","offer_id":45785889013869,"sku":"P353530824181814987","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/5693\/6301\/files\/c5b145d5e8cf064413303f388a0a1a482fcd122fe35773fe60b7ccf37b43b20e.jpg?v=1788665349","url":"https:\/\/alerano.shop\/products\/salvimar-fins-system-one","provider":"My Store","version":"1.0","type":"link"}
