I purchased a pair of Nike's last November and they started falling apart on the heel and tred. I buy my shoes and wear them until i need a new pair. After two months these shoes started to fall apart. I'm not used to buying shoes this expensive. To tell the truth i usually get my shoes from pic way shoe store and they last for a year at the least. I didn't run in them i just used them when i went to visit my mother in the nursing home. Other than that they daddy in my closet. These shoes only lasted till the end of December and like i said i only wore them when i visited my mother. I am ** yrs old and i suffer from severe asthma. I am not hard on shoes. I didn't save my box or the receipt because i buy shoes to where. I am not a collector of shoes. I buy them until i need to get another pair. I try them on and off they fit and feel good i buy them. Usually i put the old shoes in the new box and ask the store to throw them away. I've never had to return a pair of shoes. I would just like to have the shoes exchanged for the same shoe or close to the same.
