The new Cressi Gara Modular Fins and Foot Pockets utilize the conventional small rail system on the blade edges to attach the foot pocket tendons to the blade, and two small screws with a support plate that screw up into the toe plate to fix the blade in place. The support plate distributes the stress from the screw heads over a larger area and holds the blade nice and tight in the foot pocket. On the Cressi plastic blades the rails are part of the molded blade. Carbon blades must have the small rubber rails installed. The pocket is soft and comfortable. The sole is stiff and allows good power transfer to the blades. The foot pocket tendons have moderate stiffness and offer the blade good support without negatively affecting its flex pattern. The Cressi foot pockets combine well with Speardiver carbon blades.

These sizes reflect European and US numbers stated on the foot pockets. The European size is correct, but the US size may not be accurate. It's important to use the stated sizes as a reference to the foot pocket only, not necessarily as to how it fits. For example the Cressi 42-43 size is stated as US 8-9, this is blatantly incorrect. The 42-43 fits a shoe size 11 foot (actual foot length 11", width 4.25") perfectly. Albeit it is a tad tight (not uncomfortable) width wise, which makes the Cressi foot pockets nicely suitable for narrower feet. If in doubt about which size to buy measure your foot this way and provide the length and width.
Put a ruler against the wall and stand on it with your heel against the wall, measure where the furthest toe ends. In a similar way, measure the width of your foot at the widest part.
