The Zoomers Gold Fins from Finis are an excellent swim training fin to train your legs for speed and endurance and improve your ankle flexibility to improve your swim kick. The short blade design trains your legs to do shorter and faster kicks. These soft and flexible swim fins are made from 100% natural rubber and are very comfortable with an enclosed heel for a secure fit.
Theirs are so nice to wear the rubber feel so good for swimming I used them all the time ands so easy to clean then inside and out
I'm size UK 8 and this set of fins fit me perfectly. The rubber is very soft and it didn't cause any friction burns on my feet when I used it for several laps on a 25m pool. These fins definitely gives your legs a good work and allows you to feel how you should be kicking when doing front crawl / freestyle swim. I enjoy swimming with these fins and I definitely recommend these to anyone who wants to improve their front crawl / freestyle swimming technique and leg strength.
