Best for Most Big Wall Applications
Yates Big Wall Ladder
For sustained aid climbing routes and steep terrain, the Yates Big Wall Ladder is our favorite option. It features wide steps that are comfortable to stand in as you ponder your next placement and durable webbing that doesn't wear out quickly. There are six and seven-step options, with the seven-step being ideal for harder aid climbing. The Metolius 8 Step Ladder is another great option if you don't mind it missing the spreader bar. It scored up there with the Yates and is less expensive.

Metolius 5 Step Aider
We like the Metolius 5 Step. Chris Mac did most of his El Cap ascents with these and loves them, except for the fact that they blow out after a while. He usually uses the 4 Step but always takes the 5 Step on hard aid such as Reticent Wall. The Metolius is very high scoring while being one of the least expensive products we tested. If you prefer ladder style, the Metolius 8 Step Ladder would be a great option.

Best for Versatility
Yates Speed Wall Ladder
The Yates Speed Wall Ladder is a favorite for setting speed records. It's not as comfortable as the Yates Big Wall, which could be considered this aider's heavier, bigger brother. But cutting out some step width saves a bit of weight, which helps when it comes time to free climb. But this ladder has a bad habit of getting caught in cracks. It's not ideal for free-climb intensive routes like The Nose, but better suited to aid-intensive walls like Zodiac.

Best for Free Climbing Walls
Metolius Alpine Aider
For walls with abundant free climbing, like The Nose, Salathe, or Lurking Fear, lighter models are ideal. We like the Metolius Alpine for routes with minimal aid climbing because they are lightweight and not too bulky when clipped to your harness for free pitches.

Best Budget Model
Fish Smart Aider
For value, you can't beat the Fish Smart at a price per pair that rivals some individual ladders. Chris Mac did his first handful of walls with them and liked them until he started preferring aiders with more reinforced steps and more top-stepping options.

Analysis and Test Results
First off, let's get terms defined. We call an "aider" any type of webbing ladder used for aid climbing. There are two main styles: aid ladders and etriers. For a brief explanation: etrier-style models have loops on alternate sides of a main support fabric pillar, for your left or right foot, while ladder-style ones have a series of larger loops for either left or right foot with the support structures on either side, not one in the middle.
As Chris McNamara stresses in his How To Wall Climb chapters, it is your efficiency at aid leading that has the biggest effect on big wall success.
When choosing climbing gear, it's easy to get sucked into spending way too much money. Here, we help you decipher which contenders will give you the most functionality relative to their price point. We believe the Metolius 5 Step offers the best value for your dollar, as it is high-performing and one of the most affordable products in our review.
The Yates Aid Ladder with a layer of 1.75" webbing on top of 1" (the widest we tested), combined with a sturdy spreader bar at the top, stood out as the most comfortable to stand in. Second was the Metolius 8 Step Ladder. The most comfortable etrier style model was the Metolius due to the extra Biothane layer in the step, which gives it more structure to stand on while lowering the squeeze on the side of the foot. The Metolius Alpine was surprisingly comfortable for being so small. The Petzl Gradistep was the only truly uncomfortable one to stand in, but that was to be expected for such a lightweight and compact model.
Ease of Walking Up
Overall, the ladder-style models were easier to walk up than etrier-style. Most noticeable was the difference when first stepping in on horizontal pitches. The etrier-style requires that you put your foot in the correctly oriented step, which is not always the step you want at the right height. Again, with its big reinforced steps, the Yates stood out for its ease of walking up. We have noticed it is especially easy for beginning big wall climbers to get the hang of them.
The Metolius 8 Step Ladder is easy to walk up until you get to the top steps, where a lack of a spreader bar makes it a little tricky to get your feet in the top steps. The Metolius 5 Step with its reinforced steps was the easiest etrier-style model to walk up. All the products above also did well in the "fishing with your foot test", where you see how easy it is to get your foot in it the first time (without using a hand for assistance). Over time, most models without the reinforcement get harder to step into, and the steps want to stay narrower. The lightweight models like the Petzl GradiStep are the hardest to walk up, because the lack of structure makes the steps harder to get your feet into once weighted. We found we often had to use a hand to get our feet in.
If you only climb a few walls, durability is not a huge issue. All the models we tested held up for at least 10 walls. However, if you are going to climb a ton of walls, you might want to consider how well-reinforced the steps are. Overall, the Fish Smart Aider is the most bomber. After 40-plus walls, it was still going strong. After 20+ walls, the Yates models do not show much sign of wear. After heavy use on 15-plus walls, the Metolius 5 Step blew out (the stitching became abraded, causing the steps to blow out completely). This could be solved with either more bar tacks or an extra piece of webbing sewed over the key stitching point or maybe using PlastiDip. We didn't blow out any other contenders, but we also did not use them as much.
Ease of Use Free Climbing
The Petzl GradiStep is one of the lightest models and folds up into its own incorporated storage bag. It was so low-profile and light that we almost forgot it was clipped to our harness when doing free moves. In contrast, the features that make the Yates Big Wall Ladder so comfortable mean it is very bulky when clipped to your harness, and the reinforced steps easily get caught in cracks. The Metolius 5 Step doesn't get quite as easily stuck in cracks, but the reinforcement that makes it so comfy can get really stuck. The Metolius Alpine was surprisingly comfortable for being so lightweight and not bulky. Aiders without urethane reinforcement, like the Fish Smarts, are less likely to get stuck in cracks when you bust a free move or two and want to let them dangle (as opposed to taking the time to bunch them up and clip them to the side of your harness).
Overall, the Metolius 5 Step, with sub-steps in the top two steps, gives you the most options for top-stepping. It also has the highest step, so on low-angle terrain it lets you reach the highest (unless you want to put your foot in the grab loop).
Of the aid ladder style, any model that does not have a spreader bar (like the Metolius 8 Step Ladder) is very hard to get in the top steps if you are only using two in total. The Yates Big Wall Ladder was better for top-stepping, but the Metolius Ladder did have a bigger grab loop so you can get your foot in for the occasional "super top-stepping" move.
The type of aider you choose will depend on the type of wall climbing you prefer. Just as important to consider is which one would best fit your technique. Almost every product we tested excelled in a certain application or was a great value.
