This is my second pair of this model. There is a slight difference in the toe/sole. My first pair has white soles and the second pair have black. The black should be easier to clean. Initially I bought my normal men's size 12. Those were too snug so I went with men's 13s for a more comfy fit. Still wearing the first pair casually. The sole traction pattern has worn smooth but ok in iceless, non-slippery conditions. Regarding the new pair, again I ordered men;s size 13. These are more snug being new. I'g guessing they'll wear in like the first pair. Expensive but comfy!
