{"product_id":"mares-avanti-quattro-open-heel-fin","title":"Mares Avanti Quattro +","description":"\u003cp\u003eThe Avanti Quattro + diving fins have a \u003cstrong\u003eblade length that varies from 37 to 39 cm\u003c\/strong\u003e depending on the size. The fins have an open foot pocket. The \u003cstrong\u003efour ribs\u003c\/strong\u003e design allows the fins to arch during the fin stroke. The water is then channelled in the opposite direction of motion, minimising pressure loss at the side edges of the fin. Muscle power is thus transformed into propulsive thrust. \u003cbr\u003e            A new composition of the material used in the Avanti Quattro+ allows the fins to absorb energy even more easily, which is then transmitted in a better and optimised way. \u003cbr\u003eThe special \u003cstrong\u003echannel thrust\u003c\/strong\u003e system creates a channel geometry that can move more water and create more thrust with the same amount of effort. The result is an ultra-high performance fin designed for the most demanding divers.\u003cbr\u003e              The newly designed foot pocket has large perforations (which prevent the so-called \"parachute effect\") and the joints at the junction with the blade absorb kinetic energy. The blade with its extremely wide central flap ensures a strong channelling effect in accordance with the Superchannel principle. \u003cbr\u003e        Available in sizes S to XL, the new fins come in six colours: yellow, blue, black, white, lime and flamingo.\u003c\/p\u003e\n\u003cp\u003eThe main features of the Avanti Quattro + diving fins are:\u003cbr\u003e\u003cbr\u003e- 4-channel design for more propulsion\u003cbr\u003e- Highly flexible material that optimises blade efficiency\u003cbr\u003e- Channel Thrust technology\u003cbr\u003e- Thermoplastic rubber foot pocket and \"Tecralene\" technopolymer blade\u003cbr\u003e- Stabilising fins\"\u003c\/p\u003e\n\u003cp\u003eMATERIAL:Thermoplastic rubber-Tecralene®\u003c\/p\u003e\n\u003cp\u003eTYPE:Open Heel\u003c\/p\u003e\n\u003cp\u003eBLADE LENGTH:38cm \/ 15in (size R)\u003c\/p\u003e\n\u003cp\u003eBLADE THRUST AREA:780cm² \/ 120.9in² (size R)\u003c\/p\u003e\n\u003cp\u003eWEIGHT OF SINGLE FIN:0.9kg \/ 2lb (size R)\u003c\/p\u003e","brand":"Mares","offers":[{"title":"Black \/ Extra Large","offer_id":54476013470023,"sku":"MRAVQUAT-BKXL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Black \/ Regular","offer_id":54476013502791,"sku":"MRAVQUAT-RBK","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ Regular","offer_id":54476013535559,"sku":"MRAVQUAT-WHR","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ Small","offer_id":54476013568327,"sku":"MRAVQUAT-WHS","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Blue \/ Extra Large","offer_id":54476013601095,"sku":"MRAVQUAT-XLBL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Blue \/ Regular","offer_id":54476013633863,"sku":"MRAVQUAT-RBL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Blue \/ Small","offer_id":54476013666631,"sku":"MRAVQUAT-SBL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Small","offer_id":54476013732167,"sku":"MRAVQUAT-SYL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Extra Large","offer_id":54476013764935,"sku":"MRAVQUAT-XLYL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Yellow \/ Regular","offer_id":54476013699399,"sku":"MRAVQUAT-RYL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Orange \/ Extra Large","offer_id":54476013797703,"sku":"MRAVQUAT-XLOJ","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Orange \/ Regular","offer_id":54476013830471,"sku":"MRAVQUAT-ROJ","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Orange \/ Small","offer_id":54476013863239,"sku":"MRAVQUAT-SOJ","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Aqua \/ Small","offer_id":54476013896007,"sku":"MRAVQUAT-SAQ","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Olive \/ Extra Large","offer_id":54476013961543,"sku":"MRAVQUAT-XLOL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Olive \/ Regular","offer_id":54476013994311,"sku":"MRAVQUAT-ROL","price":120.0,"currency_code":"GBP","in_stock":true},{"title":"Olive \/ Small","offer_id":54476013928775,"sku":"MRAVQUAT-SOL","price":120.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/5970\/0295\/files\/mares_avanti_quattro_orange_logo_7f026e3a-7280-4bd4-9b52-5ec00db1c02c.jpg?v=1790926926","url":"https:\/\/roho.co.uk\/products\/mares-avanti-quattro-open-heel-fin","provider":"Robin Hood Watersports","version":"1.0","type":"link"}
