The Nike SB Zoom Tre is one of the newer models released from Nike SB. The model came out early 2006. Some say they can be the Nike Zoom E-Cue 2, or a good resemblance.

The Nike SB Zoom Tre has a full length phylon midsole and Zoom Air, which makes the shoe lightweight, and very comfortable. The Zoom Tre SB has synthetic ultra durable upper, so the shoe does not wear out as easy. In all honesty it seems that the Zoom Tre SB is ahead of its time.

When the Zoom Tre SB hit SB dealers, they sold for $99.99. For the quality of the shoe, you are getting your moneys worth.
