MFit: True to sizeLoving 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!
LFit: True to sizeI 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!
