I have had them since last September.  They are not showing any excessive wear. I had already tried two pair and they special ordered these for me. That shoe store being a 100 miles from home doesn't help any and after them exchanging the others and working with me I would hate to even ask them to take these back. Now if Redwing would allow me to send them back to them I wouldn't feel bad about that because I sure can't wear them for work in warm weather. I am about ready to order a pair of Wolverines from Working Persons Store online and just take a chance they are close to the old ones I have. They look real similar.
