Absolutely gorgeous shoe - only worn twice. Description from Bryr website. “The Clog just got a lot more fun!!! The Chonk is built on a sturdy solid-wood base, with a layer of shock-absorbing rubber at the bottom. The Chonk fits medium to wide, and the base height is 2 1/4". They are so fun and comfortable and a firm fave at HQ.” Color info: “Mono black has coal nubuck upper and a stained natural wood base.” Size chart: “Our sizes are US sizes, and run true to size. If you are a wide or a half-size, we recommend sizing up. Our sizes are indicated on the heel pad of the clog. Please note that the number etched on the wood heel indicates the model size, but not the clog size. Please follow your US size to find the best fit for you. If you are between sizes or a wide, we recommend sizing up on all clog styles, except high heel sandals.”
