The movements are very close to \"natural\" swimming movements. A LONG blade ensures a wider kick and a stronger muscle workout. The long blade of the TONIFINS fins makes the targeted muscles work harder.\u003c\/p\u003e\u003ch4\u003eFin stiffness\u003c\/h4\u003e\u003cp\u003eTONIFINS are semi-rigid fins. Stiffness is characterized by material density. As such, the stiffer a blade, the greater the muscle strain. The more flexible a blade, the more efficient and comprehensive the kick will be. How hard you kick will depend on the type of workout you want to achieve (cardiovascular or muscular).\u003c\/p\u003e\u003ch4\u003eWHAT ARE SWIMMING FINS USED FOR?\u003c\/h4\u003e\u003cp\u003eSwimming fins are training accessories that help to exert stronger muscle effort in the lower body. The efforts you make during exercises will improve your heart rate and strengthen your abdominal muscles and lower body (thighs, glutes, calves). The efforts you make when swimming with fins burn fat and shape your body.\u003c\/p\u003e\u003ch4\u003eAn innovation at DECATHLON\u003c\/h4\u003e\u003cp\u003eMany female swimmers use swimming fins to strengthen their legs. Conventional fins concentrate effort on the quadriceps, and the hamstrings and glutes work very little. We designed these pool fins with a blade at a 38° angle to strengthen these muscles by increasing resistance when the fin moves up and reducing effort as the fin moves down.\u003c\/p\u003e\u003ch4\u003eFOOT POCKET\u003c\/h4\u003e\u003cp\u003eTONIFINS fins have open foot pockets. Fin foot pockets hold the foot in place during kicking (important for an efficient kick). Open foot pockets allow greater freedom of movement for the ankles. Closed foot pockets keep your feet in their natural position.\u003c\/p\u003e\u003cp\u003eThese long and semi-rigid swimming fins feature an innovative blade at a 38° angle that increases the work of the hamstrings and glutes.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cdiv class=\"grid__item large--one-half medium--one-half productFeature productFeature--easy-to-breathe\"\u003e\u003cdiv class=\"grid--full\"\u003e\n\u003cdiv class=\"grid__item one-fifth productFeature-icon\"\u003e\u003cimg class=\"productFeature-image\" src=\"\" data-src=\"https:\/\/contents.mediadecathlon.com\/b72596\/pic.jpg\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"grid__item four-fifths productFeature-content\"\u003e\n\u003ch5 class=\"productFeature-title\"\u003ePropulsion\u003c\/h5\u003e\n\u003cp class=\"productFeature-description\"\u003eImprove your propulsion in the water thanks to the long blades of these fins.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"grid__item large--one-half medium--one-half productFeature productFeature--easy-to-breathe\"\u003e\u003cdiv class=\"grid--full\"\u003e\n\u003cdiv class=\"grid__item one-fifth productFeature-icon\"\u003e\u003cimg class=\"productFeature-image\" src=\"\" data-src=\"https:\/\/contents.mediadecathlon.com\/b65329\/pic.jpg\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"grid__item four-fifths productFeature-content\"\u003e\n\u003ch5 class=\"productFeature-title\"\u003eMuscular workout\u003c\/h5\u003e\n\u003cp class=\"productFeature-description\"\u003eStrengthen your hamstrings and glutes thanks to the 38° angle of the blades.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003eOur design teams developed these swimming fins for swimmers who want to build muscle in their hamstrings and glutes.\u003c\/p\u003e","brand":"DECATHLON","offers":[{"title":"çelik blu \/ UK 3-4 EU36-37 \/ 8981876","offer_id":43211371348086,"sku":"5746058","price":19.99,"currency_code":"EUR","in_stock":false},{"title":"çelik blu \/ UK 5-5.5 EU38-39 \/ 8981876","offer_id":43211371380854,"sku":"5746059","price":19.99,"currency_code":"EUR","in_stock":false},{"title":"çelik blu \/ UK 6.5-7 EU40-41 \/ 8981876","offer_id":43211371413622,"sku":"5746060","price":19.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/1446\/5398\/files\/pic_94133e8e-5121-4920-842a-7f52b528485e.jpg?v=1773977841","url":"https:\/\/decathlonkosovo.com\/en\/products\/penda-noti-tonifin-blu","provider":"Decathlon Kosovo","version":"1.0","type":"link"}
