Can anyone recommend any shopping malls near Don Muang Airport that have cheap sports gear (Trainers, T-shirts, Shorts)

Future Park is about 9km from DM, probably 10mins. if you are willing to spring for the highway. It's massive.

14ish kms away is Impact Arena Complex, with most of the branded sports wear outlets there.  Across from Cosmo Bazaar, for easy parking:

Yes been there a dozen times to eat with inlaws and the rest of the wife’s family. My wife actually bought a new 7 seat Isuzu Adventure Master car there once????

 

I’ve also been allowed to buy shorts and T shirts from there occasionally. ????

Future Park at Rangsit is really good. Not difficult to get to from DMA and there's an Ibis just across the car park lot where coukd stay if your shopping trip is a big one!

Next to ZEERS 5km from Don Mueang is kind of Bobea market, unbelievable cheap clothingh  and shoes
