The Nike SB P-Rod is the first signature shoes for the Nike SB line. Their are some great people that were apart of Nike SB that they made SB Dunks after, but they went to Paul Rodriguez.

The Nike SB P-Rods released in 2005, but Paul Rodriguez signed with Nike SB in 2004. Skaters said that the Nike SB P-Rods were the most well built Nike SB shoe to skate in. But sadly a lot of skaters though Paul Rodriquez was a “sell out” for going to a corporate company.

Even though the Nike SB P-Rods did not release in some extreme color ways like the Nike Dunk SB they sold successfully. Zoom Air is a plus always in a skate shoe (which the P-Rods have) plus a loop on the heel to easily put on.

Some nice models have came out, like the Nike SB P-Rod x Air Jordan aka J-Rod. The shoe has a Jumpman logo on the back, and elephant print. Also a Hemp P-Rod released to celebrate 4-20.
