Lightweight and True to Size — Best for Casual Use
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
It is nice to see the Amazon Essentials brand expand from household essentials to apparel and shoes.
I ordered the Amazon Essentials Men's Lightweight Knit Running Sneakers. The product is made in Vietnam and comes in a shoe box, which is nice. I've noticed that quite often, inexpensive shoes are delivered just in a plastic bag. The sneakers are ready to use and have no odors from glue, organic solvents, etc., which is common nowadays.
I wear a size 9W or 9.5. These sneakers are 9.5 and feel like a typical 9.5 size, without surprises. The product is advertised as lightweight, and it is true. Each shoe weighs below 0.6 lb (265 grams). Inside is soft memory foam; the shoes sit on the foot well, snug enough and comfortable, and are easy to put on and take off.
They seem like a good fit for spring and summer as casual footwear or for light gym use. The sole is simple and not designed for performance or high-impact activities. Overall, a solid, reasonably priced, comfortable everyday option, though not intended for serious running or training.
