I bought a pair of monkey feet to use in my gym as a substitute for some of the equipment we don’t have or can’t fit in the space (a leg extension or hamstring curl machine, for instance). They’ve been great in that capacity, but they’re also versatile as hell in a whole bunch of other capacities, and can contribute to workouts in a bunch of different ways. The only downside is the cost, which may prove prohibitive to some people. But for that price you great a very-well made piece of equipment that’s really worthwhile.

I bought my first single Monkeyfeet(MF) early this spring after using it a fair bit and liking what it's enabled me to do, I ordered a second single MF a few minutes ago so I have a pair. what I like about it: 1. portable. can use it anywhere that has some hex dumbells. My MF also was compatible with my Olympic dumbbell handles. 2. gives me access to open chain, single joint, single limb/isolateral lower body training without downsides of machines(cost/resistance curve feeling off from limb length not matching up well with machine design/locked in to whatever gym has/machines are popular during peak hours so probability is high you'd be forced to have some form of a social interaction with another human to use the leg extension machine at 5:48pm in a commercial gym) 2A. can do single joint lower body isolation in different body positions that could possibly be more functional like using wall, squat rack, or TRX for support/balance combining hip flexion/knee extension/flexion using MF and triple extension isometric of the stance leg(seems like potential good way to develop strength/control on the farther side of ROM). standing unilateral hip extension isometric with a hamstring curl(gold standard of biceps femoris isolation) 3. let's you target different "rays" within a plane of motion similar to a cable. 4. MF uses minimal storage space/floor space. if you have enough space to lay down and do a snow angel on the floor with another 1-2ft of clearance around you you probably have enough space to do just about anything you can do with MF. 5. if you're embarrassed by how horrifyingly embarrassingly pathetically weak you are, you can use monkeyfeet to train in the privacy of your home/garage gym/basement/bedroom. I'm sure there are many more strengths. These are most apparent to me off the top of my head laying on couch in my post dinner vegetative food coma mental state. Things I didn't like: 1. Doesn't work with every type of dumbbell(I'm apparently horrifyingly embarrassingly pathetically weak and I should not be lifting weights in public training facilities where I can be seen by other people due to how horrifyingly pathetically embarrassingly weak I am) and was unable to find any 5lb or lighter dumbbells around the house or at the gym with wide enough handles to be compatible with MF 2. initially I bought a single MF to see if I would like it. I found that I did like MF a lot and was irritated by having to take it off and put it on the other foot. For some movements it's just easier/more time efficient to have a pair with one on each foot at the same time.

Seems like a useful exercise tool except for the plastic release tab that broke on my first use.

I wanted to like this product because it's a great idea. But it's a royal pain to use. A re-design is definitely in order. If not applied precisely it can cause ankle pain. It may not work with all shoes. Plus changing weights quickly is really not an option. You have to plan the weight swap and be balanced to complete it. It's not that you can't do it, it's just a pain to have to stop and mess around with this during a vigorous workout. If you have limited space, live in an apartment or perhaps on vacation these might be worth the effort. But if you have a good sized home gym as I do, Monkeyfeet will not likely enhance your workouts. Sometimes you buy a fitness product that looks like it would add to your workout then find out it doesn't. This was the case for me.

Terrible. Terrible. Terrible. Just a royal pain to try and use.

Good product Sucks it costs so much. Literally tried multiple competitors and returned everyone. This works no questions asked for at least 50 lb dumbbells.

The Monkey Feet are a great concept. In practice, I find them to be clunky at best. The grip they maintain on the weights is okay. The weights have never fallen out of the "feet" but they can slide around causing the balance to be uneven. I'm a size 12 and the device accomodates only my heel so again, it feels precarious. The padding also fell off during my first use. I barely noticed a difference in comfort without the padding but it made me question the overall quality of the product.

Great rehab tool. I use it with an adjustable dumbbell and it gives me lots of options.
