Very happy with the purchase! This is my third pair and the whole family is stacking up too. Feels super comfortable, soft but still holds the feet firmly. True to size, seems sturdy, well built. The only issue was that the delivery was delayed and rescheduled couple of times. Still, it was worth it.

Quality shoes at an affordable price.

Size: 12, Color: Black/Meteor Grey

Love Asics' fit and comfort. They typically fit narrower feet like mine.

Great shoes for long hours

Size: 9, Color: Winter Sea/Black

These shoes are great for long hours standing. Comfortable, supportive, breathable, durable material that’s easy to clean. Size is true to size with large toe box. Sole and cushion are still going strong after months of use and abuse. I will buy another pair when the price is good again. Definitely worth it!
