Reebok India — Manufacturing defect of the shoes purchased from south city reebok shop

Address:

Kolkata, West Bengal

I have purchased one Reebok shoes (size USA/7.5; UK 5) from South City Mall Reebok Shop on 16.01.2016 at 7.22 p.m. But after wearing the shoes I am feeling very uncomfortable. Particularly in the hill portion. I think there may be some manufacturing defects. so my request is to do the needful so that I can be benefited.
