Desired Fit Guide

The desired fit determines the tightness of the foot pockets. Three options are available:

Comfort: Ideal for recreational dives and long training sessions. If you intend to put them on for long periods of time, choose this option. Comfortable for about 2 hours of wear.

Normal: Medium tightness, ideal for focused training sessions and competitions. Comfortable for about 1 hour of wear.

Sport: Tightest fit available that maximizes power transfer, especially for competition dives. Suitable for about 30 minutes of wear.

Choosing Bifin Stiffness

Soft: Suitable for all women, for athletes with excellent straight-leg bifin technique, and for men who want to use these fins for training and performance. Softer blades are more economic in terms of energy consumption, although it mostly remains a preference among freedivers with more strength whether to choose a soft or medium stiffness.

Medium: Can be suitable for those who rely more on the knee-kicking technique (stronger front kick due to more bent knees) and also for stronger males who use the straight-leg bifin technique. Can also be suitable for strong males who make multiple shallow dives (e.g. fun diving, spearfishing, underwater photography, and safety freediving).

Hard: Can be suitable for very strong and heavy men who dive to mid-range depths who need to overcome resistance (e.g. spearfishers diving in currents). More suitable for the knee-kicking technique.
