Blown away by the performance!

I personally switched after Rob Allen took his carbons off the market about two years ago for further development. I was in the very fortunate position of guiding trips abroad which gave me the opportunity to try out an array various client blades while asking their advice. After a season of testing I was genuinely blown away by the performance of these fins, as were the majority of my clients who used them. I’m not a massively obsessive deep diver but had these powering me up from 30m in a way that instilled confidence while keeping my energy reserves high. I experiences the same energy return while fining across the surface.

Travelling a lot ultimately gives your equipment more abuse than normal. Thrown in kit bags, left in the sun, trodden on and kicked about the boat etc. These fins have taken a fair amount of stick and are non the worse for it.

Love my Spierres!
