My normal shoe size is 8, but I should have taken this 8.5. These shoes have lasted me at least 6 months and they could last me a few more months. I work as a lube tech at a GM dealership in Southern California which is very busy and I work 2-3 days a week at my second job so these shoes have an average of 48 hour running during the work week. When trying them on, they seem very comfortable at first, but become less comfortable after a while. If this second pair lasts even 6 months I will buy them again Quality 5/5 Comfort 3/5 Value 5/5
