How to Choose Running ShoesSix numbers decide it: weight, stack, drop and width

Home › Shoes & gear › How to Choose Running Shoes

I run about 500 km a month and my marathon best is under 2:30 (sub-2.5), so here is the answer in numbers, as of Oct 27, 2026. For everyday running shoes, put three numbers in the middle: 250-285 g per shoe, about 40 mm of heel stack and an 8 mm drop (the height gap between heel and forefoot). Then shift left or right by what you run for and how wide your foot is.

The Shoe Nerd's top pick

Look at width first, not price or stack height. For everyday shoes, most models sit near the middle on weight, stack and drop, so almost any of them is close enough. The miss happens when the width is wrong. Narrow down to shoes that come in more than one width, then check the other numbers. That order fails least.

Key points

  • Across the 26 shoes on this site, the median weight per shoe is 257 g, and half of them fall between 249 g and 285 g
  • The 8 mm drop is the most common (14 shoes), within a range of 6-10 mm. The median heel stack of 12 shoes is about 40 mm
  • For width, the ASICS GT-2000 15 comes in Standard and Wide, the Mizuno WAVE RIDER 30 in 2E-equivalent and 4E-equivalent, and the HOKA Clifton 11 in Regular, Wide and Extra Wide

Choosing running shoes comes down to 6 numbers

Store displays are full of words: energy return, max-cushion, stability. But only 6 numbers matter when you choose: purpose, cushioning (stack height), weight, drop, width and size.

I took the middle numbers from the shoe articles on this site, where I read the official figures. After that, I go through what to check on your own foot.

Quick table for choosing running shoes: the numbers to aim for

What to checkThe middle numberWhich way to shift
1. PurposeEveryday jogThicker for long runs, lighter for races
2. Cushioning (heel stack)About 40mm43 mm or more if you tire easily
3. Weight (per shoe)250–285gUnder 250 g if you put lightness first
4. Drop8mm6 mm or less favors the forefoot, 10 mm favors the heel
5. WidthA shoe that comes in more than one widthWide first if it feels tight
6. Size0.5 cm stepsHalf a size up for long days
My own calculation from the 26 shoe articles on this site (men's, per shoe). The original figures are official values from each brand, and the size each weight was measured at differs by shoe, mostly around 27 cm. Stack is the median of the 12 shoes with an official heel number (about 39.8 mm). Tallied on Oct 27, 2026.

1. Purpose: split shoes by jog, long run, race, rain and wide feet

Trying to do everything with one pair means something will miss. Decide what each running day is for first.

For a first pair, the fastest start is the 6 beginner pairs, picked by weight, width and price. If you run a marathon, go to my target-time shoe guide. For rainy days, look at GORE-TEX shoes, and if width is a problem, at shoes with wide options.

2. Cushioning: read stack height from the heel number

You can read the amount of cushioning from the stack height. The 12 shoes with an official heel number range from 32 mm to 47 mm, with a median of about 40 mm, and half of them sit between 38 mm and 43 mm.

For example, the HOKA Clifton 11 has a 42 mm heel and a 34 mm forefoot. The Mizuno SKY PRIME has a 47 mm heel and a 41 mm forefoot, the thick end of this tally. If you want to soften landing impact, go for 43 mm or more. If you want a light foot turnover first, go under 40 mm.

I wrote up how to compare weight and price per millimeter in the 6 cushioned shoes, which line up only thick shoes.

3. Weight: around 250 g, your legs feel the change

Across the 26 shoes, weight per shoe runs from 220 g to 330 g. The median is 257 g, with 14 shoes under 260 g and 9 at 280 g or more.

The ASICS GT-2000 15 is 252 g, the NOVABLAST 6 is 253 g, and the Nike Pegasus 42 is about 287 g (27 cm). For everyday jogging, 250-285 g is enough. You lift your foot with every step, so the longer you run, the more lightness matters.

The size each weight was measured at differs by shoe (27 cm, 28 cm, men's US 8.5 and so on). A gap of 10 g or less can be treated as the same weight. To narrow down by lightness, my article on training shoes under 250 g is the quickest.

4. Drop: the heel-to-forefoot gap shapes how you land

Drop is the heel stack minus the forefoot stack. For the Clifton 11, that is 42 - 34, or 8 mm.

Among the 26 shoes, 8 mm is the most common (14 shoes), 7 shoes are 6 mm or less, and 4 are 10 mm (including the Ghost 18 and the Pegasus 42). The larger the number, the better it suits landing on the heel, and the smaller, the more it reads as a forefoot-leaning build. If you are unsure, 8 mm is the middle.

If your foot rolls inward on landing, whether the shoe has a support structure matters before drop does. I put those together in stability shoes.

5. Width: check the width before the length

Width is a separate number from length. The ASICS GT-2000 15 comes in Standard and Wide, the Mizuno WAVE RIDER 30 in 2E-equivalent and 4E-equivalent, and the HOKA Clifton 11 in Regular, Wide and Extra Wide. The Brooks Ghost 18 comes in D (standard) and 2E (wide) for men.

When a shoe is tight across the width, many people go up in length to escape it, but pick the wide version first. A shoe with several widths lets you choose again. Some, like the PUMA Velocity Nitro 5, come in 2E-equivalent for men and also in 3E-equivalent.

6. Size: read length in 0.5 cm steps and change it by the day

Length comes in 0.5 cm steps at both ASICS and Nike, and men's sizes run from about 24-25 cm up to about 29-31 cm. My foot is 25.0 cm.

On a marathon day or a long run, your feet swell, so I pick half a size up for extra room at the toes. I don't fix a shoe that is too narrow by changing the length. The toe area differs from shoe to shoe, so also read the fit section of each shoe's own article.

What the Numbers Say About Running Style and Pace

Shoes that sit near the middle numbers (250-285 g, a heel of about 40 mm, an 8 mm drop) read as built for easy days when you land on the heel. Most of them have no carbon plate.

The maker doesn't mark off runner levels, so this is my own reading. I read the use as anywhere from just starting out up to 3-4 jogs a week and 100-200 km a month. If you want to run faster than 3.5 hours for the marathon, plated shoes become another option.

The 4 representative pairs I chose by these numbers

These 4 pairs sit near the middle numbers and come in more than one width. The numbers are official values I read from each brand.

ASICS GT-2000 15: width and stability in one pair

At 252 g with a Wide option, it is a stability shoe. The stack is up to about 38 mm, a little thinner than the middle on the heel number. I wrote the gap from the previous generation in my GT-2000 15 review.

About the writer and sources

I wrote this as the shoe nerd: about 500 km a month, a marathon best under 2:30, and trail and triathlon races too. I re-tallied the numbers, read from the official sites of ASICS, Nike, Mizuno, PUMA, Brooks and HOKA, from this site's shoe articles. I checked them on Oct 27, 2026, and the update date is also Oct 27, 2026.

FAQ

What should a beginner look at first when choosing running shoes?

Width and weight. Narrow down to shoes that come in more than one width, then pick one that weighs 250-285 g per shoe. That rarely goes wrong. I put the 6 beginner pairs together here.

How do running shoes fit?

Sizes run in 0.5 cm steps. With a 25.0 cm foot, I look at 25.0-25.5 cm for everyday runs, and half a size up for long days. If a shoe feels tight across the width, pick the wide version before going up in length.

Do I need max-cushion running shoes?

No. The median heel stack is about 40 mm, and shoes range from 32 mm to 47 mm. Choose by purpose: 43 mm or more if you want to soften impact, under 40 mm if you want a lighter feel.

What is drop?

It is the heel stack minus the forefoot stack. With an 8 mm drop, the heel sits 8 mm higher than the forefoot. If you are unsure, take 8 mm, the most common value, as your middle.

How do I choose shoe width?

Each brand labels it differently: ASICS uses Standard and Wide, Mizuno uses 2E-equivalent and 4E-equivalent, and Brooks uses D and 2E. If a shoe feels tight, try the next width up in the same model.
