### ⭐⭐⭐⭐⭐ Review
*by R***K on 25 October 2024*

These fins are awesome, they're a little bit on the stiffer side and on the shorter side. This makes them great for traveling as you can just barely fit them into a backpack that can still pass as a personal item on a plane. The heel is very fast and easy to get on because of the spring clip. That being said these are definitely better to wear with booties as opposed to Barefoot. Propulsion and maneuverability are quite good with them as well, I really enjoyed them this far
