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.

Budget buy while being as comfy and stylish as an expensive brand!
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
My 14 year old had been running his own business since he was 12. He does lawn care and snow removal. His go to shoes when it's too hot for his work boots has always been off brand hey d*de style ones which are terrible for that kind of work as they just don't have the ankle support. He's also had some Orthopedic arch supports custom made for him through the DR in the last year that he needs to use in whatever shoes he's wearing at the time. So I've been on the search for a simple pair of slip on shoes that he could wear while working long hours around our community. He's sent me this picture tonight before heading out. He said "I didn't feel like putting my arch supports in and these are so comfy that I don't even notice I don't have them!" They are sharp looking shoes that really stand out as of they were A high end pair! It's great that they can be an every day style or could be more of a sport shoe as they have the support and padding for both options. In our case they likely be green with in a day or two and it'll be interesting to see how well they wipe off between his work days. I can update this review once he's worn them a bit more. For now they have been perfect for versatility, size was true to size (I did order 1/2 size up, but only did that because he's growing so fast!) and they are definitely a great fit to a budget!!!!

Comfortable lightweight sneakers for casual everyday wear
Size: 9.5, Color: Navy
These sneakers feel like a decent value for the price. They are very lightweight, which makes them comfortable and easy to wear throughout the day, though that also means they feel a bit less substantial than more supportive athletic shoes. I have mainly been using them with business casual office outfits, and they work perfectly well for that kind of light-duty everyday wear. I would not personally use them for anything especially active since they do not offer a ton of support, but for casual use they have been great. I also like how easy they are to slip on and off. I typically wear a size 9.5, and these fit true to size for me.
