Skechers India — shoes I bought online is I think fake

Sirs
I had purchased sketchers shoes on amozon india (Order id :[protected] on 10 july 2018 but within a month my left leg shoe torn.
I hadn't any idea of exchange policy.
Sketchers is my favourite brand till now from the date it launched in india and i had save money from my pocket money to buy these shoes but now i think i lost my money.
Yesterday my friend bought shoes from sparx (Domestic shoe company) and the store give exchange gaurantee of six months. If his shoe torn or damage he can exchange it in next six months so i think you as a reputed international brand could also help me in this regard.

And if there is any possibility please exchange my shoes.

Thanks
Your loyal customer
