EasyCare gets involved with many long distance horse treks because iron horse shoes wear faster than the hoof can grow. The hoof deteriates with nail holes and iron shoes become more and more difficult to hold in place. The horses on these treks are forced to use Easyboots out of necessity. After they start using easyboots on the barefoot hoof they see many benefits to their horses and daily travel becomes easier.
Take a look at this extreme example. 4 barefoot Suffolk Punch horses pulling 11,340 lbs of weight accross the USA. "From Montana to California by way of Boston then to Alaska in 2010".
