Finding the Perfect Fit: A Complete Sizing Guide

Never order the wrong size again with our expert guide to measuring, sizing, and fitting kitten heels.

The most beautiful kitten heels in the world won't bring you joy if they don't fit properly. Poor fit leads to blisters, pain, and shoes relegated to the back of your wardrobe. Yet finding the right size remains one of the most challenging aspects of shoe shopping, especially online. This comprehensive guide will teach you how to measure your feet accurately, navigate sizing systems, and ensure every pair of kitten heels fits perfectly.

Understanding Why Fit Matters

Proper fit isn't just about comfort—it affects foot health, posture, and how you walk. Shoes that are too small cause bunions, hammertoes, and nerve compression. Shoes that are too large create friction, blisters, and instability. In heeled footwear, fit becomes even more critical because your weight is distributed differently.

With kitten heels, the lower heel height means less dramatic weight shift than stilettos, but proper fit still significantly impacts comfort. A well-fitting kitten heel should feel secure without pinching, with your heel locked in place and adequate room for your toes.

How to Measure Your Feet

Accurate measurement is the foundation of finding the right size. Here's how to do it properly:

What You'll Need

  • Two sheets of paper (A4 or larger)
  • A pen or pencil
  • A ruler or tape measure
  • A wall

Step-by-Step Process

1. Time it right: Measure your feet in the afternoon or evening when they're at their largest. Feet swell throughout the day, and measuring at peak size ensures shoes won't feel tight later.

2. Stand correctly: Place a sheet of paper against a wall. Stand on the paper with your heel touching the wall, wearing the type of socks or stockings you'd typically wear with heels (thin socks or bare feet for most kitten heels).

3. Mark the length: Have someone mark the furthest point of your longest toe (which isn't always the big toe). Keep the pencil straight up and down.

4. Measure the width: Mark the widest points on each side of your foot (typically the ball of the foot).

5. Repeat for both feet: Most people have feet of slightly different sizes. Repeat the process for your other foot—always fit to the larger foot.

6. Measure your marks: Use a ruler to measure from the edge of the paper (where your heel was) to your toe mark. This is your foot length. Measure between the width marks for your foot width.

📏 Measurement Tip

Measure both feet and use the larger measurement. It's common to have feet that differ by up to half a size. Always fit shoes to your larger foot—you can add inserts to adjust fit in the smaller foot if needed.

Understanding Sizing Systems

Global shoe sizing is frustratingly inconsistent. Different countries use different systems, and even within systems, brands vary. Here's what you need to know:

Australian Sizing

Australia typically uses a system similar to UK sizing, though some variation exists. Australian women's sizes generally run from about 5 to 12, with 8 being close to average.

Converting Between Systems

As a rough guide for women's shoes:

  • AU/UK 5 ≈ US 7 ≈ EU 38
  • AU/UK 6 ≈ US 8 ≈ EU 39
  • AU/UK 7 ≈ US 9 ≈ EU 40
  • AU/UK 8 ≈ US 10 ≈ EU 41
  • AU/UK 9 ≈ US 11 ≈ EU 42

Note: These are approximations. Always check brand-specific sizing charts, as conversions vary.

Width Sizing

Width is often overlooked but crucial for comfort. Standard width designations include:

  • N or AA: Narrow
  • M or B: Medium (standard)
  • W or D: Wide
  • WW or E: Extra Wide

Not all brands offer width options, but many do. If you consistently find shoes too narrow or too roomy, seek brands offering width sizing.

🔍 Size Variation Reality

In a study of sizing across major brands, a "size 8" varied by up to 1.5cm in length. This is why knowing your foot measurements in centimetres is more reliable than trusting size numbers alone.

Fitting Considerations for Kitten Heels

Kitten heels have specific fitting considerations that differ from flats or high heels.

Toe Box Assessment

There should be approximately 1-1.5cm (about half a thumb width) between your longest toe and the end of the shoe when standing. This allows natural toe spread and forward movement when walking.

Pointed-toe kitten heels may feel snug at the tip while still fitting correctly—the space for toes is in the wider part of the toe box, not the decorative point. However, your toes should never feel squeezed or overlap.

Heel Fit

Your heel should fit snugly in the heel cup without slipping when you walk. Some slip at the very beginning of breaking in is normal, but significant heel movement indicates poor fit. Heel slippage causes blisters and makes walking in heels feel unstable.

Ball of Foot Alignment

The widest part of your foot (the ball) should align with the widest part of the shoe. If the shoe flexes at a different point than your foot naturally bends, you'll experience discomfort and premature shoe wear.

Arch Support

While kitten heels don't require the dramatic arch support of high heels, the shoe's arch should correspond reasonably with your foot's natural arch. Gaps between your arch and the shoe can lead to fatigue.

Common Fit Problems and Solutions

Even carefully chosen sizes sometimes need adjustment. Here's how to address common issues:

Heel Slippage

Causes: Shoe slightly too large, narrow heel, or slippery insole.

Solutions:

  • Heel grips or heel liners add padding and grip
  • Insoles can take up volume if shoes are slightly large
  • Ensure you're wearing appropriate sock weight

Toe Pinching

Causes: Shoes too small or narrow in the toe box.

Solutions:

  • Professional stretching by a cobbler
  • Shoe stretchers used at home
  • Stretching spray combined with wear
  • If persistent, the shoes may simply be wrong for your foot shape

Rubbing at the Back

Causes: Stiff heel counter or shoes needing break-in.

Solutions:

  • Moleskin or gel heel protectors
  • Gradual breaking-in at home before extended wear
  • Softening with leather conditioner

⚠️ Important Warning

Shoes that cause significant pain from the first moment aren't likely to "break in" to comfort. While mild stiffness improves, fundamental fit problems won't. Don't suffer in hope—exchange for the right size.

Shopping Online vs. In-Store

Each shopping method has advantages for finding the right fit.

In-Store Advantages

  • Try before you buy
  • Professional fitting assistance
  • Immediate comparison of sizes
  • Walk-testing on shop floors

Online Shopping Tips

  • Know your measurements in centimetres
  • Read brand-specific sizing guides carefully
  • Check customer reviews for sizing feedback ("runs small," "true to size")
  • Order two sizes if returns are free
  • Keep packaging and tags intact until you're certain of fit
  • Walk on carpet (not hard floors) when testing to ensure returnability

When Sizes Change

Foot size isn't static throughout life. Several factors can cause changes:

  • Pregnancy: Hormones relax ligaments, often permanently increasing foot size
  • Weight changes: Significant weight gain or loss affects foot size
  • Age: Feet tend to lengthen and widen over time
  • Medical conditions: Diabetes, arthritis, and other conditions affect foot shape

If shoes that used to fit no longer do, re-measure your feet rather than forcing into your "usual" size.

Brand-Specific Considerations

Different manufacturers have different lasts (the foot-shaped forms around which shoes are built), resulting in varied fits even at the same numerical size.

  • European brands often run narrower
  • American brands tend toward wider fits
  • Australian brands vary significantly
  • Luxury brands sometimes run smaller

Once you find brands that fit your foot shape well, stick with them. Note which brands work for you and which don't—this becomes invaluable when shopping online.

Final Fitting Checklist

Before committing to a purchase, ensure:

  • ☐ There's adequate room for your longest toe (1-1.5cm)
  • ☐ The ball of your foot aligns with the widest part of the shoe
  • ☐ Your heel feels secure without slipping
  • ☐ You can walk comfortably without pinching or rubbing
  • ☐ Both shoes have been tried on (fit both feet)
  • ☐ You've walked around for at least five minutes
  • ☐ You've tested walking on different surfaces if possible

Proper fit transforms kitten heels from potential torture devices into comfortable, confidence-boosting additions to your wardrobe. Take the time to measure accurately, understand your foot's unique characteristics, and never settle for shoes that don't feel right. Your feet—and your future self—will thank you.
