Yes, it can be done barefoot; but rock climbing shoes provide more friction and comfort against sharp and rough rocks during a climb. This section provides the basic parts and features of climbing shoes to assist you in choosing the perfect pair for your climbing activity.
Sole: It is the bottom part of the shoe which provides the friction needed against the surface of the climbing route.
Rand: This is the rubber layer above the sole which runs around the shoe.
Tongue: It is the flap covering the inner part of the shoe. Once the lace are tightened, make sure the flap is folded properly to conform the shin and ankle of your feet to avoid causing pressure points.
Heel: This is the bottom portion on the back of the shoe designed to cup your heel and to provide height. Important to note is that due to the added height, there will be more pressure added to your feet.
Subsidiary/Heel Loop: It helps to fit your feet in the climbing shoes and comes with different models with subsidiary loops near the heel loop.
Lining/Padding: It gives added comfort and protection for your feet.
Lace/Lacing: Different types of lacing are used by different available rock climbing shoes. A common type has eyelets or punched holes, enforced with metal grommets to prevent tearing. Other types have webbings through which shoe laces run through. Some climbing shoes provide both mechanisms. It is important that you are comfortable in your climbing shoes, no matter what type of lacing your choose.
