The stirrup is one of the most significant pieces of equipment in equestrian history. Before its widespread adoption in Europe during the early medieval period, riding was a precarious business — riders gripped with their legs and had no firm support under the foot. The stirrup changed everything, giving riders stability, leverage, and the ability to use their legs as effective aids. Today’s stirrups are highly engineered pieces of kit, available in dozens of designs for different disciplines, and the choice of stirrup is increasingly recognised as an important factor in both rider safety and performance.
How Stirrups Work
A stirrup attaches to the saddle via a leather (or synthetic) stirrup leather, which passes through the stirrup bar on the saddle tree. The stirrup hangs freely from this leather, and the rider places the ball of the foot on the tread — the flat, often textured surface at the bottom of the stirrup. The heel is pressed down, maintaining the foot in a safe position that allows the stirrup to free itself if the rider falls.
The correct position of the foot in the stirrup is important for both safety and effective riding. The foot should be placed so that the widest part of the foot — roughly at the ball — rests on the tread, with the toe pointing slightly outward and the heel down. This downward heel creates a stop that prevents the foot from sliding through the stirrup, which is a serious safety risk. The stirrup leather should hang vertically to the ground when the rider is in a balanced, neutral position.
Types of Stirrups
The market for modern stirrups has expanded enormously in recent decades, driven by both safety concerns and performance demands. The main categories are:
Traditional fillis stirrups — the classic stainless steel English stirrup with a straight tread and nickel or stainless steel construction. Reliable and inexpensive, they remain widely used for everyday riding and training.
Safety stirrups — designed to release the foot in the event of a fall and reduce the risk of being dragged. Designs include bent leg stirrups (where one side is angled to allow the foot to release), breakaway stirrups with a flexible outer band, and the Devoucoux or MDC style with open outer sides. Safety stirrups are strongly recommended by the British Horse Society for all riders, particularly children and those in early stages of learning.
Offset or angled tread stirrups — the tread is angled (typically 45 to 90 degrees) to match the natural angle of the ankle, reducing the rotational stress on the knee and hip. Brands such as Sprenger, Lorenzini, and Trust Stirrups popularised this design, and it has become standard for many serious riders. These are particularly beneficial for riders who experience knee pain.
Composite and lightweight stirrups — made from aluminium alloys, polymers, or carbon fibre, these offer weight reduction that can reduce fatigue over long rides or during competition. Show jumpers and eventers frequently use lightweight stirrups for the cross-country phase.
Western stirrups — broader and generally made from wood or plastic covered in leather. The wider tread distributes weight across a larger area, suited to the longer leg position of Western riding. Trail riding stirrups are often cage-style to protect the foot from brush.
Adjusting Stirrup Length
Getting stirrup length right is one of the first things a riding instructor will address with a new student, but even experienced riders benefit from periodically checking their length. As a rough guide for flatwork, when standing in the stirrups with a slightly flexed knee, there should be approximately 3–4 cm of clearance between the seat and the saddle. For jumping, stirrups are typically shortened by one to three holes to allow the rider to adopt a lighter, more forward position with a deeper bend in the knee. For dressage, stirrups are slightly longer, encouraging the leg to hang and weight to sink into the heel.
Stirrup length that is too short tips the rider’s weight back and restricts leg movement. Too long, and the heel comes up, the leg straightens and becomes ineffective, and the risk of the foot slipping through increases. Many saddle fitting specialists now check stirrup bar position and leather type as part of a full fitting assessment, recognising that how the stirrup hangs affects the whole riding position.
Stirrup Maintenance and Safety
Stirrup leathers should be inspected regularly for cracking, stitching failure, and thinning at the buckle holes — the points of maximum stress. Leather leathers should be cleaned and conditioned regularly. Stirrup irons should be checked for cracks or corrosion in the tread, which can become slippery when worn. Replacing stirrup leathers annually, or more frequently for horses in daily work, is sensible practice. After a fall, always check both leathers and irons for damage before continuing to ride.
Frequently Asked Questions
How do I know if my stirrups are the right size?
The correct stirrup tread width allows approximately 1 cm of clearance on each side of the rider’s boot at the widest point of the foot. Too narrow, and the foot can become wedged — a serious safety hazard if the rider falls. Too wide, and the foot can slide through, with the ankle potentially becoming trapped. Most adult riders use stirrups with a tread width of around 11–13 cm; children’s stirrups are narrower. If you ride in wide-toe riding boots, check the fit of your stirrups specifically with those boots on.
Are safety stirrups worth the investment?
Yes, particularly for regular riders. The risk of a foot becoming trapped in a conventional stirrup during a fall — leading to the rider being dragged — is one of the most serious hazards in riding. Modern safety stirrups are well-engineered, easy to use, and widely available at price points to suit most budgets. The BHS and many riding schools now recommend or require safety stirrups as standard. The cost of a good pair of safety stirrups is trivially small compared to the potential consequences of a dragging incident.
Why do my knees hurt when I ride?
Knee pain in riders frequently relates to stirrup position and angle. A traditional straight-tread stirrup forces the foot and ankle into an externally rotated position that puts rotational stress on the knee joint. Angled-tread stirrups, offset designs, or flexible tread stirrups address this by allowing the foot to sit in a more natural position, reducing the torsion on the knee. Additionally, stirrup leathers that hang behind the stirrup bar — rather than directly beneath it — push the rider’s leg forward and increase knee pressure. Checking saddle fit and stirrup bar position with a qualified saddle fitter is the most effective way to address persistent knee pain.
