Nice boots I saw A-stars' sizing chart, and Revzillas' addendum to it and was still not quite sure what size to get. I'm an 8-1/2, and would buy a boot in a 9. i tried 42 and 43, and sIze 43 is a US 9. April 15, 2013
Great riding boots for winter! I had hiking boots that were just not warm enough in the 40's for riding. I purchased these boots after a recommendation and they're great! January 21, 2013
Very Good Boot Bought these boots a few weeks ago, have been commuting daily in them. I wore them for 8 or so hours a few days, both riding and walking, and had very little discomfort. The boot seems to be made for a wider calf, I'm close to being too narrow for the velcro, but its still quite secure. Very good in the rain. Would like more venting in the summer, but for it being water tight, still not too hot. If these ever wear out, I will be buying another pair. August 7, 2012
Well made and comfortable boot Revzilla was spot on with their sizing recommendations. Size 44 fits my size 10D foot perfectly. I mowed the lawn in these twice to break them in, and they were very comfortable afterwards. Good quality construction, and after my first 4 hour, 90 degree ride, they weren't as warm as I expected them to be, being a waterproof boot. Good grip on wet/oily pavement. June 25, 2012
Great Product - Great Price A Bonus I was looking for a good quality, safe and water proof street riding boot that was not going to break my wallet. After researching I decided to pull the trigger and I have to say this is one of the best boots I've had despite it being on of the lowest cost. The quality is excellent, it is very comfortable (I need to walk around in them when doing day trips) and the boot is CE certified so no doubt it is safe. I highly recommend this boot to anyone looking for value, safety and quality. August 1, 2011

Answer: 
To accurately answer your question requires you to provide your shoe size, since the opening will vary based on size purchased.

FYI - I wear the Revit Rival H20s and love them. Have about 12,000 miles in them and they're holding up great, are super comfy, warm and dry (my review is on Revzilla somewhere). Nothing bad to say about these boots but since they're the same style of boot thought the info might be helpful. As to the calf size - I can't imagine a fitting problem with the Rivals - They have a velcro adjustment at the top and there's a pretty wide range of fit available.
