About Sherwood Spinta Open heels fins

The Sherwood Spinta fins utilize the patented Optimal Pivot Blade (OPB) technology to increase kick efficiency, minimize fatigue and maximize acceleration Effortless propulsion with optimum thrust During the kick cycle the structure of traditional fins creates a limit to the angle of which the blade can flex This limit allows only a small part of the fin blade to push water in the direction of the kick, while the remaining part pushes the water in the opposite direction, reducing the diver's forward thrust The O P B system causes the blade to flex at an optimal angle during both the upward and downward strokes This optimal angle allows the majority of the blade to push a larger volume of water in the proper direction and greatly increase efficiency All of the diver's kicking effort translates into positive thrust Traditional fins produce lower levels of thrust at different points in the kicking cycle with substantial differences between the maximum and minimum values The O P B system produces optimal thrust throughout every phase of the kicking cycle, which minimizes fatigue and produces a more fluid movement through the water

Available size: Small (SM), Regular (REG), Extra Large (XL)

    Comments about Sherwood Spinta Open heels fins:

    I purchased these fins as part of my entry-level set for my dive training in June 2010, and they are great for a beginner. I have never used a more durable fin, and they are a great value for the life you get out of them. I use these fins for diving and snorkeling, and they perform better than I anticipated. They might feel a little heavy on the feet compared to split fins, but it doesn't bother me enough to list as a con. Others may have an issue with the weight, but the good thing about having the solid fin is that you have propulsion power immediately available if you get into trouble and need to move quickly. My fins may look a little banged up after several dives in rocky areas, but they are still going strong and show no signs of wearing out. Best bang for your buck!

    Questions about this item:

    Shopper  Why Did You Choose This?
    DOUGLAS B  I bought my pair several years ago because they were on sale at the local dive shop. My son liked them better than what he used. When he asked me to send him some fins in Japan (Navy), I looked specifically for these. Leisure Pro had them, and for a good price, to boot. Now we both have our own set, and we are very happy with them.
    Aaron A  where is it made and what is overall quality.?
    VASILY B  Made in Italy. Very Good to Excellent quality. Heavier than average. Unless you have size 13-14 DD should be worn with diving shoes or heavy socks.
    Aaron A  thank you ,AAron.
