Skechers India — Skechers ..uncomfortable shoes

I purchased skechers shoes from sector 17 chandigarh store in the monthe of september. But within 2 to 3 months o[censored]sing the shoes they starting hurting my foot while walking...Ii.e...A blister is formed under my foot every time i walk with it and becomes difficult to walk further.
I contacted the customer care and explained my problem but they refuse to exchange or return . Why such a reputed brand is not providing any solution...Do we need to go to the consumer court?? kindly sort out my matter.
Thanks & regards
