An example of these are https://www.oldmillsaddlery.com/en/au/Acavallo-Fender-Mono-Stirrup-Leathers/m-72427.aspx

Judges won’t care.
Welcome to the BB.
Realistically, I don’t know if even a discerning judge could see a difference in motion with you in the tack.
A judge absolutely could. The judge just wouldn’t worry about it.
Although I don’t show in the hunter ring, or any ring, for that matter, I like to read these threads. So I consider myself an expert on this topic, and can say without equivocation that everything everyone worries about being okay in the hunter ring is okay in the hunter ring.
