    Loving my newest pair of Cariumas - this unique color works nice as a shoe with the comfort of a sneaker - I can wear them with jeans, pants, or skirts. I love the neutral color- great for travel!

    Still high quality, comfy, and perfect fit

    I bought this style for my son 2 years ago and he's still wearing them! I always liked the look of the black on black and the practicality of the black soles (no dirt shows) so decided i needed a pair for winter wear. This is my 5th Color, 6th purchase and there may be more to come. Thanks for the consistency and reliability!

"Sustainability aside, these sneakers also earn five stars in the comfort department."
