Ok so we got these guys to use in our Bouldering gym, we teach Kid's and adults the finer points of bouldering. These foot holds were such a huge step up for our students foot work and even our own, you really have to use good placement, they are way versatile and each hold has a different difficulty on them per the direction you set them, recenty we have wanted to push our climbing even more and have set routes using these as hand holds! they are perfect for working on finger strength for v10 problems, really a good way to train your fingers for outdoor climbing where you won't run into holds like you do at the gym, So we give these a 5 start review!
