Scruffy, if you have the measurements, you should be able to email them to Calevo Customer Service, and ask if any other info is needed.
My first pair of Cavallos happened to be a great steal at a local shop. So when I ordered my next pair, I used the same measurements ordering the same model. The measurements corresponded to a chart from Cavallo, based on shoe size, calf measurement and height measurement. But I did not have to hunt down that chart, I just gave my three measurements: shoe size, calf measurement, and height.
I have since ordered for different calf and height measurements, in the same model, as I got a bit more fit and needed a slimmer calf, and wanted a tiny bit taller boot, compared to my earlier boots.
I think, but I am not entirely sure, that multiple measurements as requested by Koenig will help determine if you need a fully custom boot, or if you will fit one of their “normal” custom boots. Does that make sense?
If you had the measurements done by a pro, you should be fine, and confident in placing your order. Just email all the measurements to Calevo, they will put together the Order Confirmation, and you’ll be able to verify before they submit the order to Koenig.
You can also ask Calevo to provide the size chart for the Koenig model you would like to order. I’ll post a link for the Cavallo chart that I used for the Piaffe Plus, I have it somewhere.
No matter what you decide, it will take time to receive your boots. Plan on 8 weeks, and remember that there is a long summer holiday when everything stops. Try to order in enough time to get your boots before then.
