The Olaian 900 5’4 foam surf board is a mini simmons or beater performance foamie. Decathlon follows a trend in surfing, that of the ultra short foam boards for shore breaks and wedgy waves. We tested the board and we found it very maneuverable – almost too much so! Once you’re on the board it turns so quickly. It’s easy to generate speed and it performs well in different types of waves. In bigger waves the board gets a little shaky, though. Bottom line of this review: The Olaian 5’4 is a bouncy, skatey shore break freak machine – and definitely not for newbies!
