Fins are a vital part of any stand up paddlers set up but often overlooked – the supplied skegs never being touched. And yet, if you’re after performance then experimenting with different shapes will eventually bring higher levels of shreddage.

I recently put two different sets of K4 fins (14″s and 16″s) to the test on behalf of Loco SUP – check out what I thought by hitting up the K4 fins review on the Loco site.
