This is the 3rd pair of Olympus Altra's I have owned. The other 2 pairs lasted very well and I completely wore them out. When I ordered a different style of Altra in January 2018, I ordered a size 7.5 like my other shoes that still fit. The new Altra's came and were way too big. I decided to order the Olympus style as I already had 2 of those. I ordered a 7.5 (like the ones I own and still wear) and they were so small my feet hit the end of the shoe. I returned them and got a size 8.  It fits well.  Unfortunately, after wearing them maybe 10 times, the teal edging on the left shoe is coming off. So, I am giving these only 3 stars as it seems that Altra has lost some of its quality, which is terrible as I love how these shoes fit and they are very comfortable. My concern now is that this brand-new shoe is going to fall apart on me.
