Black Diamond Women’s Momentum Lace Climbing Shoes Review

The Black Diamond Women’s Momentum Lace is honestly a big relief in a world of climbing shoes that often feel like medieval torture devices.

They are the first pair I recommend to friends who are just starting—or anyone tired of painful, tight shoes for every session. You won’t be winning any competitions for the tiniest edges or steepest overhangs, but for learning footwork, improving confidence, and racking up hours on plastic or rock, these are a pleasure.

The fit is forgiving, especially for wide feet and rounder toes. They work as a great intro shoe, a gym workhorse, or even as comfy multipitch shoes if you size right.

They’re not “miracle weapons” for hardcore sends, but they made me smile every time I could actually feel my toes after a full bouldering session.

I picked up the Black Diamond Women’s Momentum Lace because, after almost quitting on my first gym membership thanks to a pair of old-school rental shoes, I wanted to know: is there really a shoe out there that beginners can wear for hours without hating their life?

Could they actually work for more advanced climbers as a comfy training tool?

After hearing endless “get these for your first shoe!” recommendations from the gym staff, I decided to try them—with an open mind, and maybe a secret hope I could actually run laps without tearing them off between every attempt.

If you’re hunting for your first real shoe or desperately need something pain-free, I think you’ll relate to my struggles and my discoveries with the Momentum Lace.

Let’s take a look at what makes this climbing shoe unique.

Let’s be real—edging isn’t where the Momentum Lace shines. The sole is relatively flat and not super stiff, so I noticed right away that I had to actually use my foot muscles more on the tiny footholds, instead of just trusting the shoe to prop me up.

On steeper boulders with little chips, my feet felt a bit wobbly. On vertical gym walls and slabby routes with bigger footholds, they did just fine.

The first time I wore these outdoors at the local limestone crag, I tried to stand on a thin little flake that absolutely requires faith in your edge.

I could do it—but I really had to focus on putting my weight right over my toes and locking in my foot. If you like super stiff shoes that basically stand up on their own, this might bug you.

The tradeoff, though, is that this shoe helps you build better footwork, because you can’t just rely on the edge stiffness to save you. As a boulderer who abuses my feet, I found that kind of humbling, actually. But if you’re just starting or mostly using big, obvious holds, these will work great.

Now for the fun part: smearing. Maybe the best thing about the Momentum Lace is how comfy and forgiving it feels when you’re smearing up a volume or wide slab.

The sole flexes easily, so all that surface area makes contact with the wall. The rubber isn’t the absolute stickiest I’ve tried, but I feel more secure smearing in these than almost anything else in my collection (and trust me, my closet is full).

I first really noticed this on a super balancy slab route at the gym—one of those where the handholds are only psychological. I could press my feet against big panels and just relax; the shoe stayed with me.

Granted, if the walls are super slick or dusty (old gym boulder problems, anyone?), you might want to brush off your soles more often. But for practice or easy outdoor slabs, I had no complaints.

I think this is why gym instructors love recommending these to new climbers. You get that satisfying friction experience without needing a brutal break-in.

If you asked me why I love the Momentum Lace, I’d only need one word: comfort. No lie, these felt as close to street shoes straight from the box as any climbing shoe I’ve ever put on.

The knit upper breathes so well I even wore thick socks once (don’t laugh—it was freezing at the bouldering wall that morning), and my feet still fit.

No hot spots, no raw skin patches, no wincing in pain and ripping them off every ten minutes. After countless horror stories with beginner shoes, I was shocked. These are the first shoes I wore for a full three-hour session without needing a “shoe break” between every climb.

Even after a few months, they stay soft and forgiving. I did, however, notice that there’s not much “molding” to your foot over time. If the fit isn’t right at the start, it won’t get drastically better. So try them on before buying if you can.

I’ll be honest—this was a pleasant surprise. The Momentum Lace is soft enough that you feel the wall under your feet, which is awesome for beginners learning how to trust their foot placements. It felt almost like climbing barefoot compared to stiffer shoes.

On the other hand, this meant that I could feel when my footwork was sloppy, which kind of forced me to improve.

For tiny crystals or sharp outdoor nubbins, you won’t get the laser-like precision of a pricier, aggressive bouldering shoe. But for general training and gym climbing, I loved the feedback.

My one complaint is that the extra cushioning in the sole does dilute sensitivity on thin, technical outdoor climbs—but honestly, for the price and comfort, it’s a minor drawback.

Toe hooks in the Momentum Lace can be a little awkward. The fabric upper is soft and comfortable, but it doesn’t create much grip for scumming your toe on volumes. On a plastic gym roof with big toe catches, I had to try a few times before I stuck the foot, simply because there’s not much rubber coverage above the toes.

Heels are more of a mixed story. The heel cup is deep and never dug into my Achilles, but the edge is soft—good for comfort, not great for really aggressive hooks.

On an outdoor problem at my local sandstone spot, I found the heel slipping when I tried to commit weight to a marginal spike. Indoors, especially on bigger gym holds, it was fine. If most of your climbing relies on wild toe or heel hooks, you might want a shoe with stickier and more extensive rubber coverage.

But for learning these moves, or using them occasionally, the Momentum Lace does the job.

My biggest surprise was just how excited I felt to climb for hours without having to take my shoes off after every boulder problem. That made a huge difference in how much I could actually drill technique and enjoy just being on the wall.

I won’t pretend these will magically send your hardest climbs, but having a shoe that lets you forget about your feet and focus on movement? That’s underrated. My confidence in smearing and relaxed climbing soared, and I even lent my pair to a friend who’d given up on finding a not-painful shoe—she ended up buying her own.

Honestly, sometimes the best shoe isn’t the “best” so much as the one you enjoy wearing the most.

Here’s where my obsession with fit really kicks in.

The Women’s Momentum Lace is designed with a relatively wide and high-volume toe box. If you have wide feet or toes that don’t naturally bunch up (think square or Roman shapes, not pointy Egyptian ones), you’ll probably love the relaxed fit.

However, if your feet are narrow or your big toe is much longer than your others (Egyptian shape), you might feel like you’re swimming, especially around the front. The laces help cinch everything down, but it’s not magic.

In summary:

• Best for wide, medium-volume feet
• Best for square or Roman toe shapes
• Not great for narrow, pointy feet—might feel sloppy

The Momentum Lace fits best if your toes are more even in length—like Roman or Square shapes. That means your first few toes are about the same length, or your foot looks more flat across the top.

If your big toe is much longer than the others (an Egyptian shape), you might feel extra space in the toe box, especially after the shoes stretch a bit. That can make them feel a little loose or less secure on technical climbs.

Bottom line: these are a great choice for climbers with rounder or boxier toe shapes, not long, pointy ones.

Best for medium and wide feet—the toe box is forgiving and doesn’t crush wider toes, but can feel baggy on narrow foot shapes.

This is the women’s-specific version, available in women’s sizing (EU 35–42, US 4–11). Men can wear them if the fit matches their feet, but most should choose the standard or men’s model.

Sizing climbing shoes is always a wildcard, and I’ve definitely made my fair share of mistakes (once ordered three different sizes and still got it wrong!).

For the Momentum Lace, I’m a women’s street size EU 38 / US 7.5. I went with a 38.5 for my first pair, wanting all-day comfort.

That extra half-size made them perfect for gym and long sessions. I tried on a 38 for a tighter fit, but honestly, it just felt unnecessary given the soft build—going tighter didn’t magically boost performance.

Here’s my recommendation:

• Want maximum comfort (all-day gym, trad, multi-pitch)? Go up by 0.5 EU size above your street size.
• Want a snug, no-slip fit (more performance)? Try your street size, but only if you have wide feet.
• Avoid downsizing more than 1 EU size—unless you enjoy pain for no gain.

Try on in person if you can, and wear thin socks if you want to stretch the fit later.

I’m always skeptical about affordable shoes, but my Momentum Lace pair lasted way longer than I expected. After four months of serious gym mileage plus a handful of outdoor sessions, I’ve seen almost no delamination or super-visible wear.

The rubber is on the softer side, so you’ll see it rounding off at the tip after a while—especially if you drag your toes (guilty).

The laces and upper have survived a lot of dirty gym floors, getting scrunched in crash pads, and being yanked off by tired hands. I wouldn’t pick these as my only outdoor workhorse, but for the price and purpose, the build quality is surprisingly solid.

I think this is where the Momentum Lace is kind of unbeatable. You’re getting massive comfort, easy fit, and enough durability to survive most beginner (or training) mistakes for well under what most big-brand shoes cost.

Would I use these for projecting my climbing hardest problems? No. Would I buy them again as a gym training shoe, or for teaching friends, or as a comfy second pair for big multi-pitch days? Absolutely.

If you need a budget shoe that actually feels good and helps your footwork, these are almost impossible to beat.

As with anything one size doesn’t fit all. Here are my recommendations.

Probably not for you if:

• Your feet are narrow or super pointy (Egyptian type)
• You climb advanced boulders with micro footholds
• You want aggressive precision for steep, powerful moves
• You hate flat, soft shoes and need super tight performance

This shoe is for anyone who wants pain-free climbing sessions, especially if:

• You’re a total beginner and don’t want to suffer needlessly
• You have wide or boxy toes and struggle in narrow toe boxes
• You climb mostly indoors or on moderate outdoor routes
• You’re looking for an affordable backup pair or warmup shoe
