Brushing Boots & Bell Boots on bigger horses

I just got these in the mail - size Full, coral, Brushing Boots & Bell Boots. First - they seem super nice, easy to clean and sturdy. Soft fuzzy liner. I bought them NWT on eBay, as I've been wanting to try the boots for size but not wanting to spend too much $ shipping back etc if they don't work. For others - the pads in the picture are Peach, Coral, and Ginger, and the boots are Coral. I think they would work with any of these pads very nicely. These are some of my favorite colors on my dark bay horses. The Bell Boots in Full actually fit both horses ok, though my bigger horse wears size 5 shoes 🧐 not a perfect coverage but ok. The front boots will go on my Friesian - she is 17hh with good bone. They are not a great fit on her but I can make it work. The back will not pull closed except on the very edge! I don't know if they would stay on. I am still not riding due to injury so I will take photos of them on once I can tack up and ride! I would love for an XF sizing option for equine accessories! Sheets, boots, and Bell Boots! I know a lot of people have warmbloods and other larger horses so there should be a market 🤗
