Nike Air max 270 shoes

used and damaged sole when you wear it, it goes flat down.. the back part of the right shoe presses inward when walking I hear nike has an amazing warranty so you could potentially try and ask for repair or replacement. however I'm not that familiar with it so I don't know if this will be covered maybe you can take it to a cobbler to get fixed sells for 210 plus tax I don't have the receipt please note it is a damaged item and I have done my best to explain , only buy it If you are comfortable knowing it is damaged otherwise please don't buy it the item is clearly used will take offers. proceeds to be donated to my local charity :)
