Is the adjustability of these fins due to the elastic strap, or are they adjustable AND have the elastic strap. I am worried that if the adjustability is built in to the elastic only, that they will be too loose or too tight.
Which size of these fins would be fit with size 8 boots? I have another fins, Mares X-stream, those fins are size S and fit with my Mares size 8 boots,but I heard from another review, the bungee strap is so tight that some may feel uncomfortable.
Hi, The description says this is the new and redesigned model, but it also says it comes with the adjustable strap. Doesnt the new model come with the bungee strap? According to other sites, including the Mares official website, Avanti Quattro Plus do come with the bungee strap, and its also shown in the picture on this site. Which one is it?

Channel Thrust: Soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort. Mares design is inspired by marine mammals.
Latest development in Channel Thrust is the Superchannel. The blade is designed with a large flexible central Superchannel propelling water-flow more effi ciently down the fin blade instead of letting it spill over the sides for optimal performance and minimal diver effort. The limiting factors in traditional open heel foot pockets are their weight and the “parachute effect”. When finning, water gets into the space between the bootie and the foot pocket, creating drag like the air in a parachute.
The perforations prevent this and have the additional benefit of making the foot pocket very soft and flexible. Furthermore, the suction effect which can make doffing of the fins cumbersome, is now forever a thing of the past.
ABS Plus Buckles: These unique, patented buckles are the most simple and easy to use buckles available in the market. It only takes one quick movement to easily open or close the buckle, even when wearing thick neoprene gloves. The double button release prevents the buckle from accidentally opening.
Open Heel Foot Pockets: The open heel foot pocket is designed to accommodate dive boots with a sole, and to offer excellent adherence between the boot and the foot pocket in order to transfer all the force exerted by the leg to the blade, without sacrificing yield yet still ensuring superior comfort. The lower section of the foot pocket is longer, in order to better transfer power to the blade and minimize the risk of cramping. In addition, the inside of the foot-pocket features internal ribbing to improve fit and stiffen the sole.
