u must be kiddign me - Melrose is dead
...it looks like you were shopping before the stores opened.
Anyways, if you can't find anything at Heavy Hitters, Advantis Ride, The Temple of Boom, Workmens, Fat Beats, Barracuda or Brooklyn Projects, perhaps you should go east and head down La Brea to Union, Stussy, Undefeated, Volcom and American Rag---or go west and down Fairfax to Turntablelab and Supreme.
Silverlake's got Kicks Sole Provider, Eat Well, Xlarge, Wacko and Giant Robot; Echo Park's got the Anti-Market, Han Cholo, American Apparel and Brooklyn Projects East; Santa Monica's got Undefeated, Fred Segal, Horizon's West and other mom and pop shops; And Pasadena's got Grey One (and Neo39 which bridges the gap between Footlocker and sneaker boutiques), while Long Beach has Proper.
For what it's worth, addresses/phone numbers/websites/and reviews of Los Angeles-area sneaker shops can be found here:

And if none of these spots have what you're looking for, perhaps you should list all the "dope" Vancouver spots so we can get a better idea of what you're looking for. Thanks for visiting Los Angeles. We hope you enjoy your stay.
