[Resolved]  Woodland Shoes — uncomfortable to wear

i got myself woodland shoes worth 2795 Rs.One day after i felt uncomfortable in wearing the shoe.After walking 1 km pain started in my leg.Also the leaf of the shoe seemingly was a loose fit.i approached 3 days later the woodland outlet loacted in nagpur.I asked him to replace it with another model and shopkeeper refused me.He cant replace with another model replying that thing once bought is not replaceable untill it gets woren out or any defect appears.The shopkeeper was being rude in considering my case.my shoe product details are GC-287106.Its just not 500 Rs shoe,i have to bear that shoe as it cost me lots of money.
Please help,i just want to replace the shoe with another model.
