We still got about a week and a half left in March but as usual some of next month’s Nike SB releases are already starting to arrive at retailers overseas, giving us a glimpse of what’s to come in the weeks to follow.

Available now at Flatspot are four of the upcoming Nike SB April 2010 Releases. From top to bottom, left to right, you have a two SB Blazers, a SB Dunk Low and an SB Classic.

The first of the SB Blazer’s features a Matte Silver/Midnight Navy color scheme with suede throughout the base of the upper and snakeskin leather on the Swoosh and heel tab. The second of the Blazer’s comes in Black/Light Graphite and ditches the snakeskin leather for a solid suede upper. The SB Dunk Low in Obsidian/Team Red also sports buttery smooth suede on the upper, as does the SB Classic in Army Green which features perforated detailing and a leather Swoosh.

This is only a portion of the Nike SB April 2010 Releases, we’ll keep you posted on the rest of the collection when further details and images become available. For a closer look at each of these four click here.

In 2007 Nike SB teamed up with alternative rock band for a pair of sneakers which instantaneously became one of the most sought after SB’s. With their bright silver finish accented with purple, the sneakers defiantly weren’t the most fashionable at the time. Although they did have a cool little prehistoric character included on the heel which tied into the band name, something which may have helped them rise to popularity. Whatever it may have been that attracted people to the sneakers they some reason or another climbed to the top and became the grails for a lot of SB’s collectors. If you haven’t figured it out yet we’re of course speaking about none other then the Dinosaur Jr SB Dunks which Nike SB designed alongside the the Amherst, Massachusetts rock band.

Looking to generate the same buzz they did last year Nike SB teamed with the group again to work up a special edition of the new Nike SB Zoom Omar Salazar. Flipping the script in terms of colorway the SB Zoom Omar Salazar uses the purple as it’s base color, on a patent leather upper, whereas the Dunks used the hue as an accent color. The silver itself is gone completely and green comes in to take it’s place with it appearing on the inner lining, outsole, laces and outlining the tonal Swoosh. A glittery effect is used throughout the entire upper which sparkles in a variety of colors depending on the angle of light hitting them and the Dinosaur Jr. logo is seen embroidered along the heel.

We haven’t an official release details, or even really know whether or not they’ll ever be released, so stay tuned for further details as the story develops. A second show displayed the glittery rainbow effect follows after the jump. Via: NSB

For the past few weeks rumors have been floating around that the Nike SB Dunk’s displayed above were designed to honor St. Patty’s Day given their green finish, a color usually associated with the Irish holiday. In fact though those rumors have been nothing but true.

Today we’ve learned that the Green Hemp SB Dunks are actually designed by Bob Kronbauer, an art director from Vancouver, Canada and have nothing to do with St. Patrick’s Day what so ever. They’re actually inspired by the Wallenberg Palm Tree, a small tree at the foot of the 2nd step of the Big 4 at Raoul Wallenberg Alternative School in San Francisco. The Wallenberg Palm Tree has played a supporting role in skateboarding since 1990 and has appeared in a number of skateboarding videos ever since.

Below is a statement from Bob Kronbauer which he posted on Mumble giving us all the details we need to know about the sneakers and the famous tree.

The Palm Tree at the foot of the 2nd step of the Big 4 at Raoul Wallenberg Alternative School in San Francisco has played a supporting role in skateboarding since 1990. My Nike SB Dunk Low colorway is inspired by this little tree’s “Twenty Year Anniversary” in 2010/2011. Throughout the mid 90’s the tree made in appearance in most of the best skate videos of the era. Dudes were getting tech using the bottom stair as a low ledge and the second stair as a high ledge. The tree grew. In the early 2000’s people started hucking themselves down the 4, pulling tricks that would have been impressive down the first stair ten years earlier. Over the decade the tree has grown larger, like the skating going on around it. The colorway draws a palette from the palm tree itself while utilizing hemp for the Swoosh. The white midsole represents the step and has a visible “waxed ledge” around the top of it, just like that step at Wallenberg. Lastly, the insoles each contain a pixelated image of the palm tree itself, giving a nod to all of the times it has appeared in skate videos over the years.
