New Balance 1906 Sizing: 1906R, U, N, A and the 1906L Loafer

The New Balance 1906R fits true to size, and for most people there is no reason to move off your usual number. It does feel snug, though, especially through the midfoot, and that snugness is deliberate. Going half a size down usually makes it too tight, while half a size up helps only if your feet are wide.

Not every shoe with 1906 in the name behaves the same. The 1906U and 1906N are a little longer, the 1906A is nearly identical to the R, and the 1906L loafer is its own thing entirely.

Where the snug feel comes from

The 1906 is a performance runner from the 2010s that New Balance brought back as a lifestyle shoe. The part of its design you notice the most is the N-Lock system, a lacing and strap structure that pulls the upper in and holds the midfoot in place. On foot, it feels more secure and a bit more structured than a softer shoe like the 530 or even the 2002R.

Length is balanced. At your true size you will typically have about a finger's width of space in front of the longest toe, which is the amount most people want in a daily sneaker. Heel slip is rarely a problem. The tightness is across the middle of the foot, not at the toes.

Some people describe the 1906R as running small for that reason. It is worth separating the feel from the size: the shoe is not short, but it is wrapped closely around the foot.

Should you go half a size down?

You will see that advice on forums, mostly from people who like their shoes loose and find the 1906R a little long. In practice it is rarely right. At true size the shoe already fits snugly, and a half size down tends to cramp the little toe, which makes the overall fit uncomfortable. The only exception is a very narrow foot.

The other direction needs the same caution:

• Narrow, average and slightly wide feet: true to size.
• Wide feet: true to size is still the starting point. Half a size up may relieve the sides, but the midfoot structure does not open up dramatically.
• Very wide feet: this may simply not be the right shoe. A full size up adds so much length that it replaces one problem with another.

Version by version

1906R and 1906D

These share the same core fit, and both are true to size with a secure, one-to-one feel. If you are comparing sizes, order your usual number in either one.

1906A

The A is the most straightforward. The internal shape and volume feel just like the 1906R, and it lines up with models such as the 2002R in terms of length and overall room. True to size is the easiest choice for narrow, average and slightly wide feet, and very wide feet can try half a size up.

1906U

The U is roomier than the R, especially in length. True to size still works, but if you are between sizes and like a snug fit, you can carefully consider the smaller one. Half a size down sometimes feels snug in the toe box even when the width is fine, so the in-between call is hard. Colorways vary too: certain early pairs run a quarter to half size longer than later ones. Wide feet should keep their true size, since sizing down starts to pinch the forefoot.

1906N

The N sits closer to the U than to the R, with a bit more length at true size, typically about a thumb's width in front of the toes. If you are narrow or average and want a precise fit, you can experiment with half a size down. If you are wide or do not want to gamble, true to size is the safer option.

1906L loafer: size up

The 1906L does not fit like the rest of the line. It borrows from the loafer world: a thin, minimally padded interior, no laces to adjust, and a toe box that runs tight, particularly around the big toe. The common verdict from people who own a pair: order half a size or more above your normal New Balance number. Go up half a size and the heel still locks in, while the front of the shoe stops pinching.

Don't take this too far. A full size up usually leads to heel slip, and without laces there is nothing to take that up. Very wide feet may struggle with this model altogether. Remember that you will probably wear it year-round, and your feet are bigger in warm weather, so err toward the larger size if you are unsure.

How the 1906 compares with the rest of the lineup

• 2002R: true to size and a little more forgiving through the midfoot. See the 2002R guide.
• 530: roomier and softer, so the 1906R is the one to keep true to size. Read about the 530.
• 550: runs long, so you will probably move to a half size down there. See the 550 guide.
• 990: the 990 line is built differently, and many models call for a half size down. The 990 article explains.
• 9060: chunkier, with a roomier feel. See the 9060 guide.

As a general principle, New Balance models made in the USA tend to run longer, and many made elsewhere stay true to size. The 1906R behaves like the second group. Our New Balance sizing overview explains the pattern.

Nike buyers can use their usual size in the 1906R as a starting point. For example, if you wear a true-to-size Jordan 3, your 1906R is the same number. The brand size comparison gives a quick check.

Women's sizing

Women's pairs follow the same logic: true to size for the R, A and D, a little extra length in the U and N, and half a size up for the L. If you are buying a men's or unisex pair, convert first by subtracting 1.5 from your women's size. A women's 9 is a men's 7.5. The men's to women's guide covers the details.

Colorways, socks and lacing

Most 1906 colorways use the same mix of mesh and synthetic panels, so a size that works in one will work in the next. A pair with more suede or heavier overlays can feel a touch firmer across the toes, so lean toward the larger size if you are undecided about one of those.

The structure around the midfoot means lacing matters more here than in a softer shoe. Pull the laces evenly from the bottom up and let the N-Lock system do its job before you judge the size. If the shoe still feels tight across the arch with the laces slackened a little, you are probably looking at a width problem, not a length problem, and a different model may suit you better. Sock thickness has a bigger effect than usual, because the snug upper has little spare volume. Thin socks leave the fit as New Balance intended, while thick cushioned socks eat up the margin and can tip a true-to-size pair into uncomfortable.

Break-in and daily wear

The snug midfoot is the part that takes time. Out of the box, the structure can feel firmer than a softer shoe, and it often loosens up slightly after several wears. The length does not change. A fresh 1906R should feel secure and slightly snug, but never painful. Sharp pressure in the little toe or numbness points to the wrong size, not an unfinished break-in. The same sneaker fit principles apply as with any shoe.

Quick fit check

1. Lace the shoe fully and engage the structure, so the strap system is doing what it is meant to do.
2. Check for a finger's width of space in front of the longest toe.
3. Wiggle the little toe. If it feels pinned, the size or the width is wrong.
4. Walk around for ten minutes before deciding.

If you are unsure about your measurements, measure your foot and compare it against the chart below.

New Balance 1906 size chart

The 1906 line uses New Balance's standard conversions. Find the closest foot length and take that size, with the adjustment noted for the 1906L.

Example: a 27.5 cm foot is a men's US 9.5. In a 1906R we would order the 9.5. In a 1906L we would order the 10.

Final recommendation

Order the New Balance 1906R, 1906D and 1906A true to size. Consider true to size for the 1906U and 1906N as well, and drop half a size only if your feet are narrow and you like the tightest fit. Go half a size up in the 1906L loafer. If your feet are very wide, think carefully before buying any 1906, because the midfoot structure is unlikely to give.
