About Mares Flexa DS 5mm Dive Boot

The Mares Flexa DS 5mm Dive Boots have an exclusive design of the sole features a system of drainage grooves (DS Draining System), which prevent the suction effect between boot and foot pocket. Donning and doffing a fin becomes much easier. The Flexa DS Boots are ideal for those who have to cover large distances on foot to the dive site. Boots are made from durable nylon II neoprene rubber with a hard rubber sure grip sole. The complete front and the heel are reinforced with vulcanized rubber to protect this high wear area.

The heel of the boot comes with a fin strap lug to keep your fin straps from shifting while in the water. The strong and durable zipper entry allows easy donning and doffing and the zipper dam prevents water seepage through the slide fastener. All seams are glued and sewn for strength and durability and the boots top edge is taped and sewn for the same. Boots are available in multiple sizes, black in color and are covered by a 24 month limited warranty.

Comments about Mares Flexa DS 5mm Dive Boot:

These boots are well made, but don't fit me just right. I like the tread because I do a lot of shore diving where there are sharp rocks and slippery algae surfaces, and some up and down hill walks. I wish they fit me just a little better. I plan to wear socks with these.

    Comments about Mares Flexa DS 5mm Dive Boot:

    I wear an 11 shoe. Ordered 11 and had to return for 10. I have a wide foot so 10 fit well. Sole of bootie is not too bulky like some and allow good, snug fit in my Atomic, Large, split fins. The rubber heel strap retainer is positioned well, not too high or low. These worked very well in the Bahamas, since we used a large jagged reef rock to store our fish and the booties protected my feet from the jagged reef. The protective rubber coating on the top/toe works well to keep toes from rubbing inside fins along with extra durability when wearing without fins.
