There are a lot of choices available only at ABC Mart Grand Stage, including Nike Dunks, Jordans, Onitsuka Tiger, Adidas Samba, and many more.
The staff is accommodating as well. Although there may be a language barrier, they will get the items you want.
I went to the Nike Store nearby, and there was a big price gap between them, like 2000 yen for a pair of Nike Jordans.
