Ordinarily I wear a size 12 boot but this boot required a size 13 and it still is quite snug...almost too tight. I'm wearing it around the house for a day or two to better break it in. Hopefully, the boot will adjust to my foot. The "BOA" lacing system is new to me on MC boots. This will also require some adjustment on my part. It is nice not to lace and unlace these boots...saves time and grunt. Overall, the boots appear well made and certainly sturdy. A good value purchase.
