Why are my horse’s heels cracked after muddy turnout?

Overview
Cracked heels after muddy turnout are often caused by the skin being left wet, dirty and soft for too long. Mud can irritate the heels, trap moisture and make small splits more likely, especially if the horse already has sensitive skin or feathers that hold wet dirt against the area.
It can look simple, but there may be more than one cause. The skin might just be chapped and irritated, or it could be the start of greasy heel, which commonly affects the lower legs in wet, muddy conditions.
Things To Check
1. Check whether the cracking shows up after turnout in deep mud or only when the weather has been wet for several days.
2. Look closely for scabs, redness, heat, swelling, broken skin or any moist, sticky discharge around the heels.
3. Feel whether the area is sore or the horse is fidgety when you clean or dry the legs.
4. Check if the heels stay damp for long periods after coming in from the field.
5. Look at the feathering and pastern area to see whether mud is getting trapped there.
6. Consider whether the horse has recently had more clipping, washing or leg cleaning than usual.
7. Note whether the cracking is mild and dry, or whether it is spreading, crusting or becoming more inflamed.
Common Causes
The most common cause is skin irritation from prolonged wet, muddy turnout. Repeated softening of the skin can make the heels crack more easily.
Greasy heel is another common possibility, especially if there is scurf, scabs, soreness or a greasy-looking crust on the lower legs. This is often linked to wet ground and dirty conditions, but it can also be made worse by clipping, friction or sensitive skin.
Sometimes the problem is simply chapped skin from mud, frequent washing or not drying the legs fully. Less commonly, other skin issues may be involved, especially if the problem keeps coming back or does not settle with better routine care.
What To Do
Bring the horse in and gently clean off mud as soon as practical, then dry the heels carefully. Avoid harsh scrubbing, because that can make already sore skin feel worse.
Try to keep turnout areas as dry as you can, or reduce time in the wettest parts of the field if that's possible. A clean, dry stable area can also help the skin recover between turnouts.
Keep an eye on whether the cracking improves once the legs are kept cleaner and drier. If the skin starts to look more inflamed, spreads upwards, or the horse becomes uncomfortable, it's sensible to get advice.
Products That May Help
A mud and hoof care routine can be useful when wet turnout is leaving heels dirty and hard to keep clean. It may help support daily hygiene and make it easier to manage lower-leg care in muddy conditions.
