Reliable Pair of Sneakers
Size: 9.5, Color: Sea Salt/Walnut
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.
