Our Verdict

*This product has been discontinued. Check out our review of the Petzl GradiStep Etrier for going ultralight on free climbs that have short sections of aid climbing. For burly big wall aid climbing go to our Editors' Choice award winner the Yates Big Wall Ladder.

The Petzl Wall Step Etrier is an excellent choice for its comfort relative to its light weight and low bulk. In our big wall aider review it was our favorite aider for a mostly free wall such as The Nose of El Capitan. It is comfortable to stand in for the aid-intensive pitches, but light enough to forget about on the free climbing pitches. The only major downside is the price: it is much more expensive than any other aider we tested. We really hope Petzl makes a ladder aider with the same construction plus a spreader bar up top.

This is the highest scoring etrier-style aider. While the Yates Big Wall Ladder Aider is the best for aid-intensive walls, this is the best aider for walls that have lots of free climbing. If you are on a budget, get the Metolius 5 Step Aider because it is almost as good for free walls, better for aid-intensive walls, and is half the price. But if you want the best aider for The Nose or that style of big wall, get the Petzl Wall Step Etrier.

First, a note about steps

Petzl calls this a 7 Step aider but it is the same length as the Metolius 5 Step Aider. This is a good length for harder aid. However, for walls with a lot of free climbing, we prefer an aider with one fewer steps because it is less bulky and lighter when clipped to the side of the harness. Since Petzl does not make a version of this with one fewer step, we just cut off the bottom step. We've never regretted it. To learn more read our How to Choose the Best Aider and Etrier for Big Wall Climbing article.


This aider has the highest comfort-to-weight ratio of all the aiders we tested. It uses uncommonly lightweight webbing for most of the aider, which keeps the weight down. It uses a reinforced step that is 1.75 inches wide, which adds comfort. Of all the etrier-style aiders, this was one of the easiest to walk up, perhaps only slightly less easy than the Metolius 5 Step Aider. Excluding super-lightweight alpine aiders, this is the best standard size aider for free climbing. It is not only light, it is also very low in bulk for its comfort level. When clipped to the side of your harness you don't notice it nearly as much as you do with most standard aiders.

This aider has held up exceptionally well. Only after 10-plus walls has the stitching slowly started to go on some of the steps. But if it takes 10-plus walls for your aider to start to show signs of wear, you are winning. Like most (if not all) Petzl products, this aider comes with a 3-year warranty that should give you some peace of mind.

One unique feature is the Petzl String, which is an not intuitive name for the piece of rubber that you commonly find at the end of Petzl Spirit Express quickdraw. It protects the carabiner attachment point from wear. It also gives the aider a nice solid feel when clipping it to a piece. You can always take the sting off if you don't want it but I keep it on. If it wears out, you can buy a new one. Mine finally broke after about 20 El Capitan routes… so very durable.


The main dislike is the price: it is about twice as expensive as most other aiders. Other than that, the dislikes are more picky and are centered around the top step. If the top sub step were just a little higher it would be as good as the best aider for top-stepping: the Metolius 4 Step Aider. Also, the double grab loops are awkward. It would be better if they had just one that was big enough to slide your foot into. While the double top step is nice, we would rather have a double step for the second step where you spend most of your time standing. Or no double step at all and have a sub step on the second step.

Best Application

This is our go-to aider for walls that are 50-75 percent free such as The Nose, Lurking Fear and Moonlight Buttress. It is comfortable for standing around in but also light enough to be unnoticed when clipped on the side of your harness. As mentioned above, we prefer cutting off the bottom step to lessen the bulk.


At $69 this is by far the most expensive aider. If you use it a lot, it is worth the price because aiders are among the most-used pieces of big wall gear.

I bought the wall step etrier a few months ago and have used them on basic aid climbs and on the leaning tower. THey are very light and have a loop at the bottom you can bring up to clip it into the crab on the aider to make it shorter while you have it hanging on your harness. These aiders are super light and amazingly comfortable. I could stand in them all day and it wouldn't be an issue. The two problems I have with the aiders are that one the steps like to fold in on themselves occasionally and that I have doubts that they are as durable as the burlier metolius etrier or the yates wall ladders. Despite these minor quibbles I would recommend them to a fellow climber. Sure they are expensive but it is nice to have an aider that isn't bulky and is comfortable so you can move along quickly or just hang in them all day.

Bottom Line: Yes, I would recommend this product to a friend.
