Nike SB is a very limited and elite line of skateboard footwear and apparel.  Shipments drop monthly and models often sell out within a few days, sometimes in less than an hour.  Once a model is sold out you probably won't see it again.  Nike SB likes to keep things fresh by limiting production and distribution.   We won't sell these on-line so call our locations to see what we have and ask to be put on the "Nike Notifier" to get an email to tell you in advance when shipments drop.
