Mares X-Stream Fins offer comfort combined with exceptional efficiency.
This lightweight design is the result of sixty years of product development by Mares with the new, innovative Riddled Foot Pocket which eliminates parachute effect.
The X-stream is truly a leap into the future, and forever changes how we envision the creation of a fin. With groundbreaking Channel Thrust and next generation OPB Technologies it is truly a unique product.
More than 2 years of resources, experiments, testing and four Mares patents all concentrated into one product.
