The entire value of bespoke polo boots rests on one thing: the accuracy of your measurements. Every millimetre matters. A measurement that is even slightly off can result in a boot that pinches, gaps, or does not provide the stirrup control you need. Conversely, precise measurements produce a fit that is transformative: no heel slip, no calf gaps, no pressure points, just a boot that feels like it was sculpted around your leg. Because it was.
This guide walks you through every measurement we need, explains why each one matters, and gives you practical tips for ensuring accuracy.
Before You Start: Preparation
Timing: Measure in the late afternoon or evening. Your feet swell throughout the day due to gravity and activity, and they are at their largest in the afternoon. Boots built to morning measurements will feel tight by the end of a riding session. Boots built to afternoon measurements will feel comfortable all day.
Socks: Wear the same thickness and type of socks you plan to ride in. This seems obvious but it is one of the most common mistakes riders make. Measuring barefoot or in thin dress socks when you ride in thick equestrian socks introduces a consistent error across every measurement.
Surface: Stand on a hard, flat floor, not carpet. Carpet compresses under your weight and changes the geometry of your foot and ankle. Hard floor gives the most accurate measurements.
Help: If possible, have someone else take your measurements while you stand normally. Bending down to measure yourself changes your leg shape, particularly calf circumference and ankle circumference, which tighten when you flex.
Tools: A flexible fabric tape measure (the kind used for sewing, not a rigid metal construction tape). A pen and paper or your phone to record each number immediately. A flat piece of paper or card and a pen for foot length tracing.

The Essential Measurements
1. Foot Length
Stand on a piece of paper with your heel against a wall or a straight edge. Mark the tip of your longest toe (this is not always the big toe) with a pen held vertically. Measure the distance from the wall to the mark in centimetres. This measurement determines the overall size of the boot’s foot section.
Why it matters: Even a few millimetres of error in foot length can result in toes pressing against the toe box (too short) or the foot sliding forward and back inside the boot during riding (too long). Neither is acceptable for stirrup control.
2. Foot Width (Ball Width)
Measure across the widest part of your foot, which is typically the ball of the foot just behind the toes. Stand with your full weight evenly distributed on both feet. Wrap the tape around the widest point and record the circumference.
Why it matters: Foot width is where standard sizing fails most dramatically, particularly for men whose feet tend to be wider than the average boot accommodates. A boot that is too narrow across the ball compresses the foot and causes pain and numbness during extended riding. A boot that is too wide allows lateral movement that reduces stirrup precision.
3. Instep Height
Measure from the floor to the highest point on the top of your foot while standing with full weight on both feet. This is the arched area between your toes and your ankle.
Why it matters: A high instep requires more volume inside the boot’s foot section. A boot built without accounting for a high instep will press uncomfortably against the top of the foot, restricting blood flow and causing pain. Conversely, a boot built for a high instep on a rider with a low instep will feel loose and allow the foot to shift.
4. Ankle Circumference
Measure around the narrowest part of your ankle, typically just above the ankle bones. Stand with weight evenly distributed.
Why it matters: The ankle measurement determines how the boot transitions from the foot section to the shaft. A proper ankle fit prevents the boot from gapping at the transition point and ensures that the shaft sits correctly on your calf without rotating or sliding.
5. Calf Circumference
Stand with your weight evenly distributed on both feet. Wrap the tape around the widest point of your calf. Do not flex your calf muscle. The tape should be snug but not compressing the flesh.
Why it matters: Calf circumference is the measurement that determines whether the boot shaft fits snugly (correct), squeezes uncomfortably (too narrow), or gaps open at the top (too wide). For women, the widest point of the calf is typically lower than for men, so do not assume mid calf is the measurement point. Feel for the actual widest point and measure there.
6. Boot Shaft Height
Measure from the floor to just below the back of your knee while standing straight. The measuring point is the crease behind the knee where your leg bends.
Why it matters: A shaft that is too tall will dig into the back of your knee during riding, causing pain and restricting blood flow. A shaft that is too short will not provide adequate calf coverage and may slip down during play. The correct height sits just below the knee crease, allowing full range of motion while providing maximum coverage.
Critical: Measure Both Legs
This cannot be emphasised enough. Your left and right legs are almost certainly different. Studies show that the majority of people have measurably different sized feet, and calf circumference frequently varies between legs due to muscle dominance (your dominant leg’s calf is often larger). Measure every dimension for both your left and right leg independently. Bespoke construction accounts for these differences, building each boot in the pair to match its respective leg. This is one of the most significant advantages of bespoke over standard sizing, where both boots in a pair are identical.
Submitting Your Measurements
When you place an order with Polo Renoir, you receive a detailed measurement guide with visual instructions for each measurement. Submit your numbers through the guided form, and a dedicated sizing representative reviews every dimension before production begins.
If anything in your measurements looks unusual or potentially incorrect (for example, a left calf circumference that differs from the right by more than expected), the representative will contact you directly to verify. This extra step catches errors before they become mistakes in leather, saving time and ensuring the final boot fits as intended.
Include any additional information that might affect fit: specific concerns about narrow heels, high arches, bunions, previous injuries, or any other foot or leg characteristics. The more information our artisans have, the better they can tailor the boot to your body.
