It is very comfortable and is used for all-purpose climbing shoes. The cambered, or reverse curve pattern is the position of the foot in an unflexed position. This means that the toe of the shoe points down. The result of this pattern is that you can incorporate great edging in a slip lasted shoe. The shape of the shoe sole is important to the fit of the shoe, as well as the functionality.
Some shoes are very asymmetrical, meaning there is a pronounced displacement toward the big toe.
This achieves greater edging and better control on steeper routes. Other shoes are more symmetrical. These shoes are typically more comfortable, and good for longer routes. The rand is that rubber section that goes around the sides of the shoe. A good rand will keep the shoe from stretching too much, protect the sides of the shoe, and keep a sung fit to your shoe.
