UPDATE: This time the 2nd pair on the show was completely worn out in less than 3 months. not sure what has changed, still worn the same as the first pair and used in the same way. You may have to look for new options this time. very disappointed that it shows very comfortably once they are broken. 2nd pair of these for me, a little on the snuggly side of the 1st and took about a week to break in but after that I have about 6 months use of them until the soles and support wear off and that Wear is They work 12 hours a day, 5-6 days a week on concrete, asphalt and greasy floors
