Why don't you give me a call with your
measurements and we can discuss which size would work best for your horse.
Since you just pulled shoes your horses feet are going to change over
time. Since your measurements seem to be on the border I would advise
getting the larger size. One of the Easyboot 2005 design changes is a
gusseted front. This "tongue" will help the boot fit better on the hoof
and then there are the different ways the cable in the front can be configured
for sizing adjustments.
Easyboots are not recommended for your other horse
due to the 2 size differential. Again if you would like to call me with
the measurements I can discuss with you whether Boa Boots will work for
him.
