I have been reading some threads on here about eventing barefoot and note that a lot of people are concerned about traction.
This is a very real and valid issue but I have had great success using a traction trim which I have been using on a number of horses over the past 5 years.
Some people do not like the idea of adding tread to the hoof wall the way that I do, but it is effective and I prefer to keep my horse barefoot and I don't want to give up eventing.
Here is a vid of the trim being done,
Here are some pics of barefoot eventing,
