I have nothing else to suggest to you, sorry. I wish I could help though Anyway, I had to buy Tango some boots because both salt and sand hurt her feet. I bought her some from Wal-Mart, they were only $4.00 and they are insulated really well, they also have a very good rubber grip on the bottom. If any of you have a Wal-Mart store near you, I'd check and see if they have any.
