Review on Mares Avanti Quattro Plus Open Heel Bungee Strap Diving Fin by Darrell Shreves

After reading the sizing details in the comments I decided to purchase the 'regular size' due to my foot size 9 1/2 - 10 1/2 . My feet fit in completely with only a small portion of the heel being pushed out. It's not a tight fit. The bungee straps aren't adjustable, but they fit well. It will fit better if you wear booties. There is a small gap across the width. However, with a 2.0mm or 3.0mm boot, the gap becomes significantly smaller. If the Revain members hadn't shared information about this product I wouldn't have been able to find the right fit, THANK YOU! I will update this post again after testing them in open water diving. Please note that these slats are not made of plastic but of rubber.
