was at Eyechamp, in serangoon nex they have a
counter/shelf for it but I'm not sure how big the range
is,some shops for the capitol chain also do carry them.
if you're feeling adventurous, there's queensway shopping centre
. seng li or something like that have a really big range of stuff
but I'm not sure about Nike
even if they don't there's more than 10 shops if you want to
hunt around . but try to bargain harder there
