I bought the brand product of Rebok that is DMX-MAX shoe. the shoe is known for its air tubes, which is for comfort for walk or long time working. But after few months 6-7 the air tubes damaged / not working as desired. when I contacted to store ( Jodhpur base- sidhi vinayak) he told, I can't help. warranty is only for 3 months. if rebok like MNCs product failed/ damaged in few months and company didn't care the customer its really painful. its not only a question of money expended Rs 6000, but its a great deal of trust breaking.
