Size chart is intended as a guideline. Actual fit may vary. Recommendation is based on use of 5 mm boot with average sole. If you are in between sizes and have a wider foot or thicker soled boot we recommend selecting the larger size. *Weight and dimensions approximate based on black fins with rubber strap.
Customize Fit: C-series fins are stocked and offered with a specific spring strap length. For example, size L is offered with a 300 mm spring. If you prefer a more customized fit, springs are available to purchase separately in 250 - 350 mm. See Fin Accessories and Spares for more info.

Ergonomic Design Apollo Bio Fins are designed with a 20º angle to accommodate a diver's natural tendency to bend slightly at the ankle and knee. The angle is crucial to top performance and comfort. The result is maximum propulsion with the least amount of stress on the body. Apollo's choice of superior material and intelligent design provide divers with quick acceleration and the ultimate in power, speed and control.
Kicking It Wider kicks result in loss of momentum. Whether your cruising along or powering through current keep your kicks small.
Tips Avoid UV and other protective sprays and lubricants. These products are often suitable for use with synthetic rubber but contain oils that damage Natural Rubber. To keep spring strap hardware cosmetically appealing and easy to service, occasionally remove the screws for a quick brush. If necessary, add a bit of baking soda for more thorough scrub.
