There are some good toy shops around the general Da-an district mentioned, the best two are pretty close to X-Large. Theres an ok nike store just across from there it opened there pretty recently, in the last couple of months, (no SB but has some ok stuff, still had some of the atmos animal pack last time i was there, they get some jordan releases too - pretty lacking in AF1 25 stuff though
). Adidas originals is in that same neighborhood too.
For toys pixie is definitely worth a look http://www.pixie.com.tw/
its slightly away from Da-an just accross dunhua south (towards sogo)
Also fyi Sweemie will begin to carry the Futura "Modified" line that was previosly only available in Thailand (or off egay).
