I inherited some Dsakine's on a used board I bought. How do you tell which model they are?
The supremo's have a urethane like webbing (internally) and are incredibly soft on the feet whereas the Primo's have the standard hard webbing. Both have the same neoprene covers but the supremo's are worth their weight in gold. I recently grabbed some Primo's and the difference is noticeable but not that bad in comparison with the stock ones that come with most boards.
