I would say my calves are med/muscular build and my feet are quite small(6). So the 6 fit fine at the foot but did not fit over the calves. My calves at the biggest are 14” in circumference (36.5 cm) and these could not be zipped up. I think you have similar calves and have had trouble fitting into other boots of a similar style you already know that about yourself and possibly like myself will try and delude yourself into thinking that this time it will be different. I looked for reviews to tell me this and didn’t find it so I got them and just ended up in a long return process so let me save you the trouble; look for another style. Perhaps the Damned-318 or Swing-815 something that is slightly more adjustable because these will NOT work for you. Sorry. Until Demonia offers this style with an elastic slit we will have to pass.

Don't get me wrong, I love the Shaker 100, but the 65 does offer a lot more wearable options that maybe wouldn't work with a taller boot. The fit of this boot is amazing! I have athletic calves and they are definitely tight to zip up, but are still super comfortable to wear. They don't slip down a ton either!

They are true to size; I usually wear a 8.5 so I ordered a 9 and they're spot on!

Super comfortable. I’m normally a 6.5 so I got a 7 so I can wear thick socks! Perfect fit!

These are for my 19 yo. She loves them.

I got a size 11 and they are tight on me I also have bigger calves so maybe I should have sized up :/ or maybe ill succumb an just endure the suffering
