Understanding Different Heel Types
Before diving into the measurement process, it’s essential to understand the different types of heels. Each type may require a slightly different approach for accurate measurement.
* **Stiletto Heel:** A tall, slender heel, typically thin from top to bottom.
* **Block Heel:** A wide, sturdy heel that provides more stability.
* **Wedge Heel:** A heel that extends along the entire length of the shoe, providing continuous support.
* **Cone Heel:** A heel that is wide at the sole and narrows towards the bottom, resembling an inverted cone.
* **Kitten Heel:** A short, slender heel, typically no more than 1-2 inches high.
* **Spool Heel:** A heel that is wider at the top and bottom and narrower in the middle.
* **Platform Heel:** A heel combined with a platform under the forefoot, reducing the perceived pitch.
* **Cuban Heel:** A short, slightly tapered heel, often found on boots or oxfords.
* **Louis Heel (Pompadour Heel):** A curved heel, wider at the top and curving inward before widening again at the base. Named after Louis XV of France.
* **Stacked Heel:** A heel made of layers of material, often wood or leather.
Tools You’ll Need
* **Ruler:** A standard ruler with millimeter or inch markings.
* **Measuring Tape:** A flexible measuring tape for curved surfaces.
* **Digital Caliper:** A precision instrument for accurate measurements, especially useful for small or intricate heel designs. (Highly Recommended)
* **Right Angle:** A set square to ensure the ruler or caliper is perpendicular to the base of the shoe.
* **Flat, Level Surface:** A stable surface to place the shoe during measurement.
* **Pencil and Paper:** For recording measurements.
* **Shoe Last (Optional):** A foot-shaped form used in shoe manufacturing; helpful for maintaining the shoe’s shape during measurement.
Method 1: Measuring Heel Height with a Ruler
This is the most basic method and suitable for most heel types. However, it may not be as accurate for complex or curved heel shapes.
**Step 1: Prepare the Shoe**
* Place the shoe on a flat, level surface.
* Ensure the shoe is standing upright and the heel is stable.
**Step 2: Identify the Measurement Points**
* The starting point is the point where the heel meets the upper part of the shoe (the vamp or the quarter). This is usually the back of the heel.
* The ending point is the bottom of the heel, where it makes contact with the ground.
**Step 3: Position the Ruler**
* Place the ruler vertically against the back of the heel.
* Ensure the ruler is perpendicular to the flat surface. Using a right angle can help with this.
**Step 4: Take the Measurement**
* Read the measurement on the ruler where it aligns with the point where the heel meets the upper part of the shoe.
* Record the measurement in millimeters or inches, depending on your preference.
**Step 5: Account for Platform (If Applicable)**
* If the shoe has a platform, measure the height of the platform at its thickest point (usually under the ball of the foot).
* Subtract the platform height from the total heel height to get the effective heel height. This represents the actual elevation your foot experiences.
*Effective Heel Height = Total Heel Height – Platform Height*
**Example:**
* Total heel height: 4 inches
* Platform height: 1 inch
* Effective heel height: 3 inches
Method 2: Measuring Heel Height with a Measuring Tape
This method is useful for measuring curved or irregular heel shapes where a ruler might not provide an accurate reading.
**Step 1: Prepare the Shoe**
* Place the shoe on a flat, level surface.
* Ensure the shoe is stable and upright.
**Step 2: Position the Measuring Tape**
* Start at the bottom of the heel where it meets the ground.
* Carefully follow the curve of the heel with the measuring tape, ensuring it stays in contact with the surface.
**Step 3: Measure Along the Heel**
* Continue measuring along the back of the heel until you reach the point where the heel meets the upper part of the shoe.
**Step 4: Read and Record the Measurement**
* Read the measurement on the measuring tape at the point where it aligns with the upper part of the shoe.
* Record the measurement in millimeters or inches.
**Step 5: Account for Platform (If Applicable)**
* As with the ruler method, measure the platform height and subtract it from the total heel height to get the effective heel height.
Method 3: Measuring Heel Height with a Digital Caliper
A digital caliper provides the most accurate measurements, especially for small or intricate heel designs. This is the preferred method for professionals.
**Step 1: Prepare the Shoe**
* Place the shoe on a flat, level surface.
* Ensure the shoe is stable.
**Step 2: Zero the Caliper**
* Close the jaws of the caliper completely.
* Press the zero button to calibrate the caliper.
**Step 3: Position the Caliper**
* Open the jaws of the caliper and position them so that one jaw is at the bottom of the heel and the other jaw is at the point where the heel meets the upper part of the shoe.
* Ensure the caliper is perpendicular to the base of the shoe.
**Step 4: Take the Measurement**
* Gently close the jaws of the caliper until they make contact with the heel at both the top and bottom points.
* Read the measurement displayed on the digital screen.
**Step 5: Record the Measurement**
* Record the measurement in millimeters or inches.
**Step 6: Account for Platform (If Applicable)**
* Measure the platform height with the digital caliper.
* Subtract the platform height from the total heel height to get the effective heel height.
Tips for Accurate Measurements
* **Use a Level Surface:** Ensure the shoe is placed on a flat, level surface to prevent skewed measurements.
* **Check Perpendicularity:** Verify that the ruler or caliper is perpendicular to the base of the shoe. Use a right angle for assistance.
* **Apply Consistent Pressure:** When using a caliper, apply gentle and consistent pressure to avoid compressing the heel material.
* **Take Multiple Measurements:** Take several measurements and calculate the average to minimize errors.
* **Consider Heel Angle:** For angled heels, measure the vertical height, not the length along the angle. The vertical height is what affects the shoe’s pitch.
* **Account for Heel Tip:** The heel tip (the small piece of material at the bottom of the heel) should be included in the overall measurement.
* **Differentiate Between Total and Effective Heel Height:** Always specify whether you’re providing the total heel height or the effective heel height (after accounting for the platform).
* **Use Consistent Units:** Stick to millimeters or inches throughout the measurement process to avoid confusion.
* **Document Your Process:** If you are measuring multiple shoes, keep a log or spreadsheet with shoe style or ID and corresponding heel height measurements.
Common Mistakes to Avoid
* **Measuring at an Angle:** Measuring the heel at an angle will result in an inaccurate reading. Always ensure the measuring tool is perpendicular to the base.
* **Ignoring the Platform:** Failing to account for the platform height will overstate the actual heel elevation.
* **Compressing the Heel:** Applying too much pressure when using a caliper can compress the heel material, leading to an underestimation of the heel height.
* **Using Inaccurate Tools:** Using worn or damaged measuring tools can compromise the accuracy of your measurements.
* **Measuring on an Uneven Surface:** An uneven surface can cause the shoe to tilt, affecting the accuracy of the measurement.
* **Rounding Too Early:** Avoid rounding measurements until the final step. Rounding intermediate values can introduce significant errors.
Practical Applications of Heel Height Measurement
* **Shoe Design and Manufacturing:** Heel height is a critical specification in shoe design and manufacturing. Designers use heel height measurements to create prototypes and ensure consistency across production runs.
* **Retail and E-commerce:** Retailers use heel height measurements to accurately describe shoes in catalogs and online listings. This helps customers make informed purchasing decisions.
* **Footwear Research:** Researchers use heel height measurements to study the biomechanics of walking in high heels and to develop interventions to prevent foot problems.
* **Custom Shoe Making:** Custom shoe makers rely on accurate heel height measurements to create shoes that fit perfectly and provide optimal comfort.
* **Podiatry:** Podiatrists use heel height measurements to assess the impact of different shoe styles on foot health and to recommend appropriate footwear for patients.
