I have a few sets of rails which will fit all the above mentioned fins/blades. The thin rails perfectly fit footpockets such as OMER, Sporasub, Picasso and Spetton. The wider rails are for water channeling. They are in my opinion an improvement over the old yellow Matrix fin rails. The set comes with 8 precut rails to replace all the rails on a pair of blades/fins, that's twice what you see in the picture and the best glue for the job directly from the manufacturer. $15 each set. They are easy to glue on so no worries.
