can you walk in climbing shoes?

You can walk in climbing shoes, it is just not recommended. Climbing shoes are not meant for walking, they are meant for climbing. Walking in them can just wear the shoes out quicker. Not to mention that they are also pretty painful to just walk in.

A lot of climbers like to walk in new climbing shoes to help stretch them out and break them in, so that could be an exception to the above. After those shoes have stretched, though, it would just be wearing them out quicker.
