ORIGINAL Jackson Matrix Elite ice figure skate blades replacement runners multiple sizes available This item is a package of two replacement runners for the ORIGINAL (older mounting system) Jackson Ultima Matrix Interchangeable Blade System. These are the Elite model, I believe with an 8" rocker and a 7/16" ROH. It is only the replacement runners, not the mounting hardware or the blade holder. Please make sure that your blade holders will take this older model of replacement runners, because I do not take returns. Please see photos or ask questions for more information. I am not a store, just a skating mom who is trying to help clear some excess stock at the rink and raise some money for the skating club. Therefore, no returns unless I have misrepresented something, in which case, please contact me. US shipping only. I am willing to combine shipping on items, but please notify me before paying so I can issue an invoice with the combined shipping amount.
