The only pair of Altras that I have returned. This pair felt loose on the inside of my foot next to my arch. It was the particular style on my particular foot. I love Altras and own several pairs.I absolutely love altra shoes and have never given less than five stars to a pair. These ones, however, seem to fit much tighter than all my previous pairs. It’s the first time I’ve tried this particular model and besides the more snug fit, I am very pleased with them. They have such amazing cushioning that it feels like running on clouds. I would definitely recommend, but consider sizing up from pairs like the escalate.Not only are these more narrow but they also run small in length! These soles are the Rivera2 size 8.5 compared to the Escalate 3 size 8. I really like the look of these, I hope Altra makes these with their standard width. Other than that, these are too cushioned for me, they felt like they had minimal arch support.I wear only Altra athletic and Torin 5 leather work shoes--zero drop and wide toe box, my feet never hurt even after 8 hours standing and walking. I'd like a thicker cushioned sole, and more durable (the soles compress after about 6 months, though I do wear them alot). Overall I budget for these as essential to my comfort and health.I own several pairs of Altra trail running shoes size 7. I am between 6 1/2 and 7 and always go with the 7. The size 7 on this particular shoes is one whole size smaller. What is up with that? In my other Altra, I have a lot of room even with thick wool shock on. The 7 on this model is more of a 6. Definitely returning.Fits your foot and very comfortable.This is my 3rd pair of Altra tennis shoes. I wear size 9 but this fits more like a size 8. Fortunately, I was able to return them for a refund. I love the look for the tennis shoe won’t keep them.direi che sono come me le avevano descritte..formidabili..
