Flex Boot replacement shell in sizes 80-120, sold individually without gaiters or back straps. To order a pair, please add replacement shells into your basket.


These are the replacement shells for Flex Boots, the softest hoof boot on the market. If your boot shell is damaged but other components are in good condition, or your horse's hoof size or shape has changed so the old boot doesn't fit them anymore, you can simply purchase a replacement shell and attach the components from your old boot to the new shell.


Flex Boots are durable and comfortable, and easy to put on and take off. They are carefully designed with the horse's wellbeing as the top priority. Thanks to the careful design and advanced technology used to make these boots, they are suitable for use in any weather and terrain; with great drainage and water-repellent materials, Flex Boot’s supportive yet soft materials mean you can use them in snow, wet mud, very dry conditions and anywhere in between.  The all-terrain sole gives superb grip, and the boots have pre-drilled holes that allow for easy application of snow or grass studs if this is required.


Flex Boots are easy to clean and maintain – simply rinse off any dirt and hang the boots to dry in a well-ventilated place. They are ideal for first time users and perfect for all equestrian activities including trail riding, schooling, jumping and driving.
