Brand new, unused item. Authentic Japanese authorized dealer product. While labeled as XL size, those who find Mick's L size fins suitable may prefer these fins. Conversely, the Medina L size fins are relatively small, so those who find Mick's L size fins perfect might find these a bit small. The Medina fins have a slightly smaller center fin in this XL size (see image 4). They provide solid hold on bottom turns and relatively smooth top actions. ↓ Riding footage of the GUCCI store manager... *You can view it by copying the link below and searching on Google or Yahoo. https://www.instagram.com/reel/DJWABNNSbz3/?igsh=a2pocDZwNDc1dnUz Performance Core surfboard fins designed for Gabriel Medina. - Brand: FCS - Model: GM (Gabriel Medina) - Size: X-LARGE - Material: AirCore - Series: Athlete Series Thank you for viewing.
