Help please -Chippewa snake boot sizing

[S-3 Ranch]

I had a pair of the mock toe chipps, they ran a little big. Prolly 1/2 a size down

The regular old viperhide , non zipper, cowboy toe....I'd go up 1/2 size

I got two pair of regular viperhide I switch out getting revamped @ Chippewa, 1/2 size up sounds about right
I wear 9.5-10 walking shoes

Using one of those foot measuring contraptions, my size measures 11.5 EE... That's what I bought for my first pair of Chips... They fit perfect, and I've gotten several more pair since then. However, I always buy the original Chippewa's... Other styles will vary I'm sure. The zippered ones most likely will be different as they are NOT USA made. Not sure any Chipps are USA made any longer since they were bought out. It's hard to find 'em in stores or on line now!! Last year, I switched over to Danner's because I could not find Chipps...
