Brooks Size Guide
Brooks is a well-established running footwear brand known for consistency, predictability, and a signature plush, comfortable fit. The brand offers a comprehensive range of running shoes—from daily trainers to race-day speedwork shoes—plus running apparel and accessories. Brooks shoes are renowned for their true-to-size fit with ample toebox space in most categories, though performance-oriented race shoes deliver a more glove-like, snug feel. Whether you're a seasoned runner or new to the sport, Brooks provides options across multiple widths and fit profiles to suit different foot shapes and running goals.
How to Measure
- For shoes: Measure your foot length in centimetres using a ruler or measuring tape. Stand barefoot on a flat surface with your heel against a wall, and measure the distance from the wall to the tip of your longest toe. Repeat for both feet, as they may differ slightly.
- For upper-body clothing: Measure your chest circumference across the fullest part, keeping the tape measure parallel to the ground and not too tight. Wear a fitted layer for accuracy.
- For waist measurements: Measure around your natural waist (the narrowest part) without pulling the tape too snugly.
- For lower-body clothing: Measure your hip circumference at the fullest point of your hips and buttocks, keeping the tape parallel to the ground.
- Compare your measurements against the size charts below. If your measurements fall between two sizes, consider the fit style: choose the smaller size for a snug, race-oriented fit, or the larger size for everyday comfort and recovery shoes.
- Visit a specialist running store whenever possible for a professional gait analysis and fitting. Expert staff can recommend the right shoe model and width for your foot type and running style.

Product-Specific Guidance
Running Shoes: Daily Trainers, Stability Shoes & Recovery Shoes
Brooks daily trainers (such as the Ghost and Glycerin) and stability/recovery shoes are engineered for comfort and support. These shoes typically feature a relaxed, accommodating toebox (95–97 mm in width at the widest point on a men's US size 9) and are designed for true-to-size fit. Order your normal running shoe size, or go half a size to one full size larger than your dress shoe size. The plush cushioning and signature step-in feel make these shoes ideal for long training runs, easy recovery days, and everyday running.
Running Shoes: Race & Speed-Oriented Shoes
Brooks race shoes and tempo trainers (including the Hyperion Elite and similar speed-focused models) deliver a glove-like, snug fit with a narrower toebox (92–95 mm on a men's US size 9). These shoes are competition-grade and prioritise responsiveness over comfort. If you are ordering a race or speed shoe, go 1.5 sizes smaller than your usual running shoe size. Always test race shoes well before race day.
Unisex Race Shoes
Some Brooks spikes and race running shoes are offered in unisex sizing, which is based on men's sizes. Women should note the Women's (W) equivalent listed on the product—for example, M6.5/W8. The Women's size is approximately 1.5 US sizes larger than the Men's size in the same EU number.
Stealthfit Upper Technology
Brooks releases selected daily trainers (such as the Glycerin and Levitate) in both standard mesh and Stealthfit knit variants. Stealthfit uppers provide an adaptive, sock-like fit that feels lighter and airier on the foot, and often shave grammes off the standard shoe weight. Fit and length remain consistent between the two variants, so size accordingly as you would for the standard version.
Running Apparel & Accessories
Brooks running clothing—including upper-body tops, lower-body tights and shorts, and sports bras—follow standard letter-based sizing (XS through XXL). Measure your chest, waist, and hip circumference as described above and cross-reference the clothing size charts. If your measurements fall between two sizes, select based on fit preference: choose the smaller size for a snug, racing-focused fit, or the larger size for relaxed, everyday comfort.
Sizing Tips
- Order running shoes half a size to one size larger than your dress shoes. Brooks running shoes are designed with more toebox space and cushioning than formal footwear, so sizing up is normal and recommended.
- Always measure your foot length in centimetres at home. This is the most reliable method. Stand barefoot on a flat surface with your heel against a wall, measure to the tip of your longest toe, and compare the result to the foot length column in the shoe size chart.
- If you already own running shoes from ASICS, New Balance, Saucony, or Nike that fit well, you can typically wear the same size in Brooks. Brooks sizing is consistent with these mainstream running brands, though individual shoe models may vary slightly.
- Race and speed shoes run noticeably smaller and tighter. These competition-focused designs are not suitable for all-day wear. If purchasing a Brooks race shoe, go 1.5 sizes smaller than your standard running shoe size and test it thoroughly before race day.
- Brooks offers generous width options: Narrow, Medium, Wide, and Extra Wide. If you have a narrower or wider foot, explore the full range of width letters available for your chosen model. Many popular styles come in multiple widths at no extra cost.
- Visit a specialist running store for a professional fitting. Expert staff can perform a gait analysis, assess your arch type and pronation, and recommend the most suitable Brooks shoe model and width for your individual running style and foot biomechanics.
- Allow time for shoes to break in. Brooks shoes are renowned for comfort, but a short 1–2 week breaking-in period is normal. Wear new shoes for short runs or walks first before using them for longer distances.
- Check the size and width code on the shoe label. Brooks clearly marks the shoe size and width letter (e.g. "UK 8 D" for a men's medium-width shoe). Verify this matches your order before leaving the store or before the return window closes.
