Not for all surfaces.
Size: 11.5 Wide, Color: Black Leather/Optic White
The sneakers look great and are comfortable on flat, smooth surfaces. Warning: The sole is very flexible and not well cushioned so a walk on rough or uneven surfaces can become uncomfortable quickly. Just understand the limitations.

Comfort Meets Coastal Style – A New Favorite Tee
Size: X-Large, Color: Dark Heather
The Costa Del Mar Costa Topwater T‑Shirt is everything you want in a casual, everyday shirt. The material is super soft and lightweight, making it perfect for warm weather or long days outdoors. It feels breathable and comfortable without being too thin.
The fit is spot on—true to size with a relaxed feel that doesn’t look baggy. The design is clean and stylish, with that classic Costa vibe that’s perfect whether you’re out on the water or just hanging out.
After multiple washes, it’s held up great—no shrinking, fading, or losing its shape. You can tell it’s made with quality materials that are built to last.
If you’re looking for a comfortable, good-looking t-shirt that represents a laid-back coastal lifestyle, this one is a great pick. Definitely worth it!

Great shirt, runs a tad small
Size: X-Large, Color: Navy
Great looking shirt and good value for the money. Depending on your build you may want to order a size larger. I'm 6'4" and 207. I typically wear an XL and ordered an XL. It fits me but is a little snug there is not much room in the shoulders and sleeves or body for that matter. If I were back to my previous weight of 245 with a larger waist I would have to return it and get a XXL.
