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!!!!

Good purchase.
Size: Medium, Color: Black, Size: Medium, Color: Black
My daughter needed some black sweaters for work at Starbucks. Came across these and snatched one. Price was really good, it is soft, black color is vivid and did not fade after washing. Durable and well-made. Fits as expected...she wanted something loose on her to wear on cold nights over her shirt. Keeps her warm. It came pretty quickly. The material is soft and its comfortable to wear. Nice basic sweatshirt to have in your closet! Pleased with purchase 😊 hopefully this helps!! Oh we intentionally bought bigger for an oversized fit.

Customer Favorite for Comfort & Everyday Wear
Size: 4X-Large, Color: Safety Green, Size: 4X-Large, Color: Safety Green
I absolutely love the Fruit of the Loom Men’s Eversoft Fleece Crewneck Sweatshirts! These have quickly become a staple in our store because they deliver exactly what our customers want — comfort, durability, and a clean, classic look. The fleece is incredibly soft on the inside without being too heavy, which makes it perfect for everyday wear, layering, or working outdoors. One thing I really appreciate is how breathable and moisture-wicking the fabric is. Even after hours of wear, it still feels comfortable and not overly hot, which is important for active days or changing temperatures. The fit is true to size and the extended sizes up to 4X are a huge plus. It’s not always easy to find quality sweatshirts in larger sizes that still look good and hold their shape, but these definitely do. They wash well, keep their softness, and maintain their color without shrinking or fading. If you’re looking for a dependable, comfortable sweatshirt that looks great and feels even better, this is a solid choice. Whether for casual wear, work, or relaxing, you really can’t go wrong with this one. Highly recommend!
