I'm not convinced these are authentic Sperry Top-Siders.  My son wore these to school for 2 days and the glue or something in the sole of the shoe is making noise - both feet.  It's like the glue is cracking where the bottom of the shoe meets the leather.  Every step he takes you hear a creaking sound.  Also, he wore white socks with them and the dye in the leather bled all over the socks.  The socks were completely reddish brown (ruined).  I can't imagine that Sperry is making a product so poorly.  I'm going to attempt to send these back as defective.
