Sold on ASICS for my running needs.
Size: 8, Color: Carrier Grey/Anzu
I run 40+ miles a week. These running shoes are terrific. Can afford the expensive brands/models and this fits my feet, price and running requirements. Have purchased several over the years.

Comfort and Great for Standing
Definitely the best shoe for standing on ur feet all day. I stand for about 7.5 hrs a day and this has changed things for me drastically. The foam makes a difference and the shoe is stylish as well.

ASICS Gel Running Shoes – Comfortable, Lightweight & Perfect for Gym and Running
Size: 10.5 X-Wide, Color: Black/White, Size: 10.5 X-Wide, Color: Black/White
I recently tried a pair of ASICS Gel sneakers, and I’m really impressed. They are extremely comfortable, with great cushioning that makes a big difference during workouts. I’ve used them both at the gym and for running, and they perform very well in both situations.
The support is excellent, and they feel stable without being too heavy. I especially like how they absorb impact when running, which helps reduce stress on my feet and knees. They also have a nice fit and feel breathable, so my feet don’t get too hot.
Overall, I’m very happy with them. If you’re looking for comfortable and reliable sneakers for the gym and running, I would definitely recommend ASICS Gel shoes.
