Boreal Synergy Review

The Synergy is an excellent choice for bouldering outdoors and indoors. It manages to retain the advantages of a soft shoe - sensitivity, maximum contact and flexion - whilst maintaining enough stiffness and precision to perform well on edges, as you would expect from a stiffer shoe. In addition it's comfortable, albeit fairly high volume and, whilst specifically a bouldering shoe, it's a great choice for any rock (or plastic) type.
