  • To make it easy to put the socks on and take them off, two holes – one near the toes and one in the instep of the foot – are strategically placed on the socks. These are vent holes, and not defective.
  • By using the power of your leg, the fins will create greater propulsion power with little force, to enable effective kicking and swimming while maintaining stability and buoyancy on the water surface.
  • Do not walk or stand on sandy beaches or any rocky surface while wearing fins unless it is necessary to do so. Walking and standing on land with fins may cause you to fall and lead to serious injury or accident. Additionally, walking and standing on land with fins may scratch and damage the fin blades. Please make sure that the strap is not broken before each use.
  • Do not remove fins on rocky surfaces or while snorkeling.
  • In case you need to walk with the fins, please walk slowly backward while checking your surroundings carefully. Walking with fins is dangerous and if you walk in a forward direction there is a greater possibility of falling.
  • Make sure that the fin buckles and straps are securely in place. If you find any defects, please stop using it immediately.
  • Adjust the strap securely in place. Please do not over tighten or loosen it too much as doing so may cause the fins to fall off or result in serious foot injuries.
  • When choosing a full foot fin, please choose the size that best fit for your snorkeling use, such as bare feet, snorkeling shoes, or snorkeling socks. Please refer to the fin size chart for the best fit. Using incorrect sized fins and foot pockets may result in not obtaining the full propulsion power of the fins, but may also cause serious damage to your feet and skin.
  • Before ore using the fins for the first time, it is recommended to wipe off any oily film on the fin blade surface with a soft cloth.
We recommend our Super Anti-Fog Treatment (TEC-52A) or any aftermarket anti-fog solutions on ReefTourer masks.
After use rinse your equipment in fresh clean water and dry thoroughly before storing. Take care that any purge valves or snorkel tops are free from sand and debris that can cause leakage.
