Will not work without additional parts. I think someone in the factory messed up the labeling process, these shoes run WAY oversized! Would rather have a velcro and buckle system even for freeride/dh shoes. Ending up returning it which I was charged $20 for shipping , haven?t received any credit yet ;(Doesn?t meet the standard of Nike ! Things just arent made like they used to be. Im replacing an older lifestyle system, and nothing is forward compatible. I searched and contemplated the best spice storage option for WEEKS and finally decided to get this, and I couldnt be happier. I wear slippers most of the time because I stay at home most of the time but I also go outside into my back yard to replenish the food I put out for the birds. I like that they are elastic probably due to my skinny feet? Nevertheless I feel like some more wear will be needed for the perfectly comfortable fit.
