buy shoes from custom will be getting a import tax of at least 30%, plus 10% sales tax.

See whether which method you bring in the items.
if via air freight, then that would be alot easier
u can get at KLIA, Cargo terminal, POS MALAYSIA building.

If via sea friehgt, then thats abit trouble compare to air freight.
u have to see which Kastam office to hold your items.
Caz Klang port got few office. and you must refer to the proper office to get your stuff.

note: your goods which being holdup in sea port, will definately take ALOT longer time to retrieve your goods. Unless you have your freight agent take care of the goods.
