About a year and half ago I purchased Nike Air Max 180 Basketball sneakers, after about a years use, one day after coming down from jumping the air unit in the heel expanded almost like a little ball and caused me to severely sprain my ankle, I went to the hospital and took pictures of everything, I then contact Nike and followed their instructions in which I sent them medical records and the sneakers, they admitted they had a defective sneaker. Now they want to offer me only $1000, I am inclined to take this offer due to the fact that I still have weakness and pain when playing, and on the account of them not reimbursing me for the time I missed for work. I need advice someone please help me, should I counter-offer?
