Wow, that's wide. FYI, Cavallo Simple Boots are very round.. Mine are 5 1/2 x 5 1/2 inches. Just a bit too large for my up to 5" max W or L feet. Can you use them? Lol
Do give Amber a shout. Tell her AppyT sent ya, I met her on the equisearch forum.. lol
She does not remove sole or frog unless it's a real tatter etc., then only what wants to come off. Perhaps there is flaring that is making them too wide. If you check her site she has an online service which consists of email convo and viewing pics you can send her before you have her out if you wish. Take them asap since they were just trimmed as that will help her know what's going on best via pics.
Here is a shot of my fatround tries to be underrun filly's foot after her last 2 trims. Compare if you like.. I think these are both a left front.
