Description

FlexMini Ahti Pastern Strap

The Ahti Pastern Strap is part of the FlexMini Ahti fastening system, designed to stabilize the upper part of the boot.

It attaches to the Rear Unit and wraps around the front of the pastern, helping keep the boot correctly positioned during movement.

Designed for stability and freedom of movement

The Pastern Strap works together with the rest of the Ahti system to:

  • Maintain correct upper alignment of the boot

  • Prevent excessive vertical movement

  • Support a secure fit without restricting joint flexion

When adjusted correctly, it keeps the boot stable while allowing natural movement of the pastern and fetlock.

When to use

Replacement Pastern Straps are available if:

• Your current strap is worn or damaged
• You need a spare set
• You are maintaining or rebuilding your boots

Each FlexMini Ahti boot includes a Pastern Strap as standard.

Sizing

One size fits all FlexMini Ahti boots (60, 65, 70, 75).

The strap can be adjusted to fit different pastern sizes.
Excess length can be trimmed after fitting for a clean finish.

Fit & Adjustment

For correct function:

  • About one finger should fit between the strap and the leg

  • The strap should sit evenly at the front of the pastern

  • The fit should be snug but not restrictive

  • The tail of the strap can be secured neatly

Correct adjustment supports stability without limiting natural movement.

Material

Made from high-quality thermoplastic polyurethane (TPU), combining flexibility, strength, and durability.

The material flexes with movement while maintaining a secure hold.

Care

  • Rinse or brush off dirt after use

  • Allow to dry in a ventilated area

  • Avoid harsh chemicals

  • Avoid storage in high heat or enclosed spaces

FlexMini Ahti boots are available in sizes 60–75, designed specifically for miniature horses and ponies.

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 length from the toe backwards. Put the zero at the edge of the toe, and measure straight back along the centre of the hoof. Measure to the back edge of the heels.

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.
