I have no number stamped on the any of my balances. I checked all three windows. I think it's either 351 or 391. They look the same in the pictures.

I'm afraid I can't make out which Series would be a better match. The different comes down to the size of the shoe. We have detailed information and measurements on the S351-24 and S390-24 store pages that you can review. You will need to measure your shoe and use your best judgement, since the difference is subtle, but important.
