Finding the right shoe size is important for comfort and performance. Use the Topo Athletic size charts below and follow our measuring guide to find the right size.
Topo Athletic shoes tend to fit slightly smaller than standard sizing. We recommend choosing half a size larger than your usual shoe size.
Topo Athletic shoes use US sizing, shown in the left-hand column of the size chart.
Please note: The measurements in centimeters refer to the insole length, not your foot length.

How to Find Your Topo Athletic Size
A running shoe with the right fit is important for both comfort and performance. Follow the steps below to measure your feet at home and use the Topo Athletic size chart to find your size.
Remember that the centimeter measurements in the size chart refer to the length of the insole, not the length of your foot.
Tips Before Measuring
- Measure your feet in the evening, when they are usually at their largest after a full day of activity.
- Measure both feet. If your feet are different lengths, use the measurement of the longer foot.
- Wear the socks you normally use for running when measuring your feet.
- Topo Athletic shoes tend to fit slightly smaller than standard sizing. We recommend choosing half a size larger than your usual shoe size.
- If you are between two sizes, choose the larger size.
What You Need
- A piece of paper larger than your foot
- A pen or pencil
- A ruler or measuring tape
- The socks you plan to wear with your running shoes
How to Measure Your Feet
- Place a piece of paper on a flat floor with one edge against a wall.
- Stand on the paper with your heel against the wall. Wear the socks you normally use for running.
- Mark the position of your longest toe on the paper.
- Measure the distance from the wall to the mark in centimeters.
- Repeat the process for your other foot.
- Use the measurement of your longer foot when choosing your size.
- Compare your measurement with the Topo Athletic size chart above. Remember that the CM measurement in the chart refers to the insole length.
Topo Athletic Fit
Topo Athletic shoes are designed with a roomy toe box that gives your toes space to spread naturally, combined with a secure fit through the midfoot and heel.
When trying on your shoes, your toes should have enough room to move comfortably and should not feel restricted.
For the best starting point, choose half a size larger than your usual shoe size, as recommended for Topo Athletic shoes.
The size chart is a guide. The ideal fit can vary depending on your foot shape, the socks you wear and the Topo Athletic model you choose.

Topo Specter 3 Women
The Topo Specter 3 for women is a lightweight, max-cushioned performance trainer built for runners who want more energy and speed from their everyday training. As the first shoe in Topo's Pro Series, the Specter 3 introduces an entirely new underfoot experience designed for up-tempo sessions, faster long runs and days when you simply want to pick up the pace.
At the heart of the shoe is Topo's new RevFoam™ ATPU midsole, delivering high energy return while keeping weight impressively low. The max-cushioned platform has been increased to 39 mm in the heel and 34 mm in the forefoot, providing plenty of protection for harder and longer efforts. A redesigned rocker geometry encourages quicker transitions and a faster toe-off, while the ATPU insole adds another layer of rebound directly beneath the foot.
Despite its generous cushioning, the Specter 3 weighs just 6.3 oz (approximately 179 g) in a women's US 7, giving it a remarkably light and agile feel. Topo's signature roomy toe box allows the toes to spread naturally, while the secure midfoot and heel help keep the foot comfortably locked in as the pace increases.
The updated outsole provides improved traction and durability, making the Specter 3 ready to handle both fast workouts and consistent weekly mileage.
For runners looking for a highly cushioned shoe that feels light, responsive and genuinely fun when the pace increases, the Topo Specter 3 brings a new level of performance to the Topo line-up.
Why we recommend the Topo Specter 3
