We speak of underrun heels when the heel walls are left too long and as a result the heels grow further and further forward. This has meanwhile become a common problem in horses, and is already referred to as a kind of disease of civilisation.
If the heel walls are left too long, the heels grow further and further forward. The corner struts, which are also too long, lever the sole upwards, while the pads are squeezed inwards. This results in a "pushing under" of the heels. The end edges of the heels should actually be on the same level as the widest part of the frog, but instead they are more or less far in front of it.
Underrun heels are often found in connection with very long, flat hooves and pressing corner struts.
Is hoof protection recommended?
Many Hoofstar customers ask whether the Hoofstar glued shoe can also be used with the underrun heels. Short answer: Yes, the Hoofstar glue-on shoe can also be used for underrun heels.
However, the Hoofstar does not guarantee that the underrun heels will improve. An experienced hoof care professional must work hand in hand with the horse. Only with correctly trimmed hooves will the situation of the underrun heels improve.
