The One4Life® Slim all-in-one car seat takes your child from birth to big kid with trusted Britax safety, ClickTight® installation, and a slim SpaceSaver™ design. As a convertible and harness-2-booster seat in one, it grows with your child for 10 years. It starts rear-facing with an extended capacity of up to 50 lbs., so your child can ride rear-facing longer. It easily converts to forward-facing toddler mode (up to 65 lbs.) and high-back belt-positioning booster mode (up to 120 lbs.) when your child is ready. With a slim outside and spacious inside, the 17.5” seat is designed to fit 3 across* without compromising safety and comfort. ClickTight helps you install with confidence, every time. The base and shell are easy to wipe down for hassle-free cleanup. The car seat cover is safe to machine wash and dry, and it’s naturally flame-retardant with no added FR chemicals. One4Life Slim features a high-strength steel frame, a SafeCell® crumple zone, and a V-shaped tether. As your child grows, you can easily adjust the 15-position no-rethread harness and headrest with one hand. With cooling channels, premium padding, three infant inserts, and built-in armrests, your child will love every ride.

The perfect work shoe
Size: 13, Color: Black Leather
I wear dress shoes everyday and I’m on my feet a lot. My wife is the same way and would always praise Clarks, but I didn’t think much of it. I’d always get Nunn Bush or something like that, but they weren’t comfortable or last very long. I happened to be at a Clarks store that was closing one time and picked up a pair of these and boy did everything change that day. Not only are they comfortable they last a long time. I get about one pair a year. That doesn’t mean they only last a year, I just try to keep a nice looking pair. I can wear them all day and my feet don’t hurt. And you get all the comfort without the bulkiness of other comfort footwear companies. They fit nice and don’t pinch or rub anywhere. They are definitely worth the full price, but they go on sale regularly to an even better deal so keep an eye out.

Classic elegance with unmatched comfort
Size: 11 Wide, Color: Black Leather, Size: 11 Wide, Color: Black Leather
I recently purchased the Clarks Men's Oxford shoes, and I must say, I am thoroughly impressed. These shoes effortlessly blend classic elegance with unmatched comfort, making them a perfect addition to any wardrobe. The first thing that caught my attention was the timeless design. The Oxfords feature a sleek silhouette and high-quality leather craftsmanship that exude sophistication. Whether paired with formal attire or dressed down for a more casual look, these shoes consistently elevate my style. Beyond their aesthetics, the comfort level is exceptional. The cushioned insole provides excellent support throughout the day, making them ideal for long hours on my feet. Additionally, the outsole offers a confident grip, ensuring stability on various surfaces. I also appreciate the attention to detail in the stitching and overall construction. It's evident that Clarks prioritizes durability, and I believe these shoes will stand the test of time. One minor aspect worth mentioning is the initial break-in period. Like most high-quality leather shoes, they required a few wears to conform to my feet perfectly. However, once they molded, the fit became incredibly comfortable. In conclusion, the Clarks Men's Oxford shoes offer a winning combination of style, comfort, and durability. Whether for formal events or daily wear, they consistently deliver a polished and refined look. I highly recommend these Oxfords to anyone seeking a timeless and reliable footwear option.

Great shoe for the price
Size: 9, Color: Black
My son needed a dressy pair of shoes. Decided to try these for the price. He loves them and has worn them several times. They still look great and he says they're comfortable. We ordered his regular size and it fit perfect. We’re very happy with this purchase.
