I actually had to much room in the heel of the shoe and there was no way to adjust my foot to fit, they actually felt like flip flops. I would order a size up as they run smaller than stated, I am discouraged as due to covid, you cant go to stores to try things on and if you want to replace, you have to go to a store to return them to sellers or Amazon. Some did not seem very stable. They have great tread, perfect for climbing up the Xunatunich ruins in Belize, and he did not get any blisters despite wearing them on this 4 hour hike for the first time. I was walking and running around a ton and never sat down once for hours. I love the look of them, and would actually consider ordering another pair for outdoor use, but Im going to wait to see what the comfort is like first. Ive been hunting for the "every day" sneaker and I think Ive found them. These are all metal and not plastic so everything is very strong. Eventually I was certain it was doing the same issue I had before. Even if you arent a techie.
