i used to use the SMB boots for years. about a year ago my trainer had me switch to polo wraps bc she didnt like SMB boots. Looking back, i dont think that the smb boots really support the horses legs. I have the older style SMB boots, but i think that i like the new SMB boots better. they seem more fitted and molded to the horses legs. I now use the Equifit T-wraps. they are really cool and lots of support. you do have to know how to put them on correctly, but i agree that it would be hard to screw up a horses legs using polos, but i have seen it done. sooo, overall i like polos, plus you can clean them better and more frequently than boots. (I suggest t-wraps, but they are like $90 dollars)
I love Alexis, Bindi and Maggie!
