Protect and toughen your horse's feet. This aldehyde-based formula thickens the cell membranes of the exfoliating sole, which in turn thickens and toughens the horse's sole and frog. Durasole is a great choice for horses with weak feet, or for horses transitioning from shoes to barefoot. Since this formula doesn't dry out the hoof, it can be used for extended periods of time. The antibacterial and anti-fungal properties are great for treating thrush and white line disease, or just for prevention. Durasole is extremely effective in preventing and relieving sole soreness, making it a great candidate for any equine athlete!
