PlanetFoot Size Guide
At PlanetFoot, we believe that finding the perfect pair of shoes starts with understanding your unique fit. As a leading retailer of sneakers and athletic footwear, we understand that shoe sizing can be confusing, given the global variations between UK, US, and EU systems. Our sizing philosophy is built on comfort, consistency, and fit accuracy. We recommend always referencing your foot measurements alongside our charts, as the best fit is always a personal one. Whether you are selecting a pair of running trainers or casual sneakers, this guide will help you confidently choose the size that supports your comfort and style.
How to Measure Your Feet Accurately
- Gather Materials: You will need a piece of paper, a ruler, and a pen.
- Measure Both Feet: It is crucial to measure both your left and right feet. It is extremely common for one foot to be slightly larger than the other; always size up to fit your largest foot.
- Timing Matters: Measure your feet in the late afternoon or evening. Since feet naturally swell throughout the day, measuring when they are at their largest provides the most accurate size.
- The Measurement Process: Place your foot on the paper, heel first. Have a helper trace the outline of your foot, ensuring the tracing captures the longest point of your heel, the ball of your foot, and the longest toe.
- Record the Length: Measure the distance from the back of the heel to the tip of the longest toe. Record this measurement in centimetres (cm) and inches.

Product-Specific Fit Guidance
Our footwear range is designed for diverse activities. Keep these fit notes in mind when selecting your perfect pair:
- Running Sneakers: For optimal performance and injury prevention, we recommend choosing a size that allows for a thumb's width of space between your longest toe and the shoe tip. As your feet swell during long runs, a slight extra room is beneficial.
- Casual & Lifestyle Sneakers: These shoes often feature a snugger fit. If you are between sizes, we advise sizing up by half a size (e.g., from a 9 to a 9.5) to ensure comfort throughout the day.
- Boots & Hiking Footwear: Due to the nature of hiking and traversing uneven terrain, these shoes require maximum space. Always size up and ensure the shoe is roomy enough to accommodate thick hiking socks without restricting circulation.
Essential PlanetFoot Sizing Tips
- Measure in the Evening: As noted above, your feet can swell throughout the day. Measuring in the late afternoon or evening will give you the most accurate, largest measurement.
- The Larger Foot Rule: If you have noticeably different sizes for your left and right feet, you must purchase shoes that fit your larger foot. Never size down for comfort.
- Consider Activity: For athletic shoes (running, training), always factor in swelling and movement. A shoe that fits perfectly when standing still may feel too tight during exercise.
- Brand Variation Warning: Be aware that different shoe manufacturers use different 'lasts' (the mould used to shape the shoe). If you are buying a specific brand, check their dedicated size guide, as our chart is a general guide.
- Half Sizes Matter: Do not ignore half sizes (e.g., 38.5 or 41.5). A half size difference can make a significant impact on toe room and overall comfort, especially in performance footwear.
- Return Policy Confidence: If you are unsure of your size, remember that PlanetFoot offers a hassle-free return policy. We encourage you to order your size and try it out at home for the best fit.
