UP, VELCRO OR SLIPPER?
Generally, for long days, long sessions at the wall, and beginners, a lace-up is the way to go, as it provides a good distribution of pressure along the foot and is comfortable for long periods of time. Slippers are ideal for bouldering, as they can be taken off and put on easily between problems, giving your feet a chance to air. Velcro shoes are often a good all round option, for those who boulder, trad climb, sport climb and use indoor walls.
