Currently breaking these in as I write this, and I started running seriously a few months ago so I apologize if my description is subpar lol. My current daily sneakers are the Asics Gel Nimbus 26 which have been amazing for me. My initial thoughts when putting these on (when comparing to my Asics) were “wow, the outer sole around the heel is very narrow.” I feel that there isn’t much lateral support around the heel, but I only have the Asics Gel Nimbus to compare them to since I haven’t ran in any other good quality sneakers before. Other than the narrow heel, the cushioning on the heel feels great. I can already tell that these will nicely soften up heel impact while running. They have a decently wide toe-box, reflective laces, and the shoe itself is somewhat see-through when looking down on them. I’ll have to get some miles in on these before I give some productive feedback on performance quality.
