Description
FlexMini Ahti Replacement Shell
The Ahti Replacement Shell is the base structure of the FlexMini Ahti boot.
It forms the sole of the boot and provides the foundation for movement, traction, and protection.
What it is
The shell is the load-bearing part of the boot.
It includes:
-
The sole and tread pattern
-
The built-in breakover
-
The flexible structure that allows natural hoof movement
All other components of the Ahti system attach to the shell.
How sizing works
Ahti uses a modular sizing system.
The final boot size is created by combining the shell with the Rear Unit:
-
60 shell + 60 Rear Unit → size 60
-
60 shell + 65 Rear Unit → size 65
-
70 shell + 70 Rear Unit → size 70
-
70 shell + 75 Rear Unit → size 75
Available shell sizes
-
60–65 shell
-
70–75 shell
Each shell is designed to work with its corresponding Rear Unit range.
When to use
Replacement shells are available if:
• The original shell is worn or damaged

Important to note

Replacement parts are available through our retailer network.
FlexMini Ahti uses a modular sizing system. Each size is created by combining the boot shell with the correct Rear Unit to achieve the final dimensions.
Boot sizing is based on the internal width of the boot, with the length proportionally longer to match the natural shape of miniature hooves.
Our boot measurements are taken from the inside of the boot shell, so it’s easy to compare them directly to your hoof measurements. Hooves should be measured shortly after a fresh trim.
If the hoof measurements are exactly at the upper limit of the boot measurements, and the horse has large heel bulbs, it is advisable to choose the next size up or use pads for adjustment.

Measure the width from the widest part of the hoof, with the tape measure perpendicular to the centre line of the hoof.

Now, compare the hoof measurement to this FlexMini Ahti size chart.

Materials
The boot shell, TPU gaiter and back strap are made of thermoplastic polyurethane (TPU), a material that is often called a hybrid between plastic and rubber. TPU offers the flexibility of rubber, but with the strength and durability of plastic. Neoprene gaiters are made soft but durable neoprene with laminated fabric on both sides. Rivets are made of steel. Pads are made of EVA foam. Extension straps are also made of TPU.
Care instructions
Flex Boots are easy to clean and maintain. The TPU material keeps its elasticity and lasts longer if the boots are in regular use. After using the boots, simply rinse off any dirt and hang the boots to dry in a well-ventilated place away from direct sunlight. Do not store the boots in a closed space such as a box or in your car. The boot shell, TPU gaiter, and back straps can be brushed clean and washed with water. Do not use cleaning products.
Neoprene gaiter can be rinsed with water or washed in a washing machine in a cold cycle. Air dry only, do not tumble dry.
Pads can be rinsed with water after use to remove any debris.
Do not use any cleaning products to clean the TPU parts.
We have retailers all around the world, so ordering from a Flex Boot stockist near you might be more convenient than ordering from our store which is located in Finland.
