Description 

IST FP01 Sumi Open Heel Fins

Sumi was designed with propulsion efficiency in mind.

Utilizing different materials’ flexibilities and structural improvements such as water channelling guides on the blade and the 22º blade-to-foot angle, IST is able to create fins that are not hard on the legs yet generous forwarding force will always be provided.
The fin’s foot pocket is also the product of IST’s time-consuming research and manufacturing experience. This is an often-neglected criterion when divers choose their fins and the we are confident that SUMi will be one of the most comfortable fins that people put on.

Hello, The IST Sumi Open Heel Scuba Fins are made to fit a 5mm boot. A boot that has a rubber sole, that is tennis shoe like. The size medium fits a men's size 8-9. Although, if you have a slimmer style boot, you should go down a size. Hope this helps! Sincerely, Jamie Customer Service
