FASTSKIN KICKFINS

* Uses 3D foot form scan technology to create Speedo’s best ever fitting fin, maximising comfort and power transfer from greater overall foot contact- so you can swim faster with less discomfort for longer
* Short dual rail blades capture more water during the kick, giving enhanced energy transfer from your kick to the water compared to a flat fin, resulting in greater propulsion
* Dual material construction makes the fin 40% lighter* for faster turns and reduced hip flexor soreness * vs nearest competitor fin
* Tread pattern added on sole of foot to give additional grip on turns and when diving off blocks
