These New Balance sneakers are really comfortable and have a clean, stylish look that works for both casual wear and light activity. Fit is true to size and they feel supportive, though they could use a little more cushioning for long hours on your feet. Overall, a solid and reliable pair of sneakers.

Best sneakers on amazon!

Size: 10.5, Color: White/Light Blue

Best sneakers on amazon ever. I bought them on sale for around $45 and do not regret it at all. They are of superior quality and fit amazing. Comfy to wear all day and seem like they are going to last quite awhile. Very easy to clean as well.

This is my second time buying these shoes, just in a different color. These are my favorite going out shoes for comfort, look, and overall quality. They look very clean and are great for the price! Lots of compliments on these shoes!
