With its funky flip-down heel and soft sock-like fit, the Session is a comfy and convenient slip on/slip off shoe for bouldering and sport climbing, inside or out. It's too casual for longer or more rugged approaches, but in its niche we think it's a bit of a winner.
Obvioulsy they're not the cheapest, but I've really rated them.
Funnily enough I used a different pair of shoes whilst climbing down at the Cornice the other day and was saddened that I couldn't just slip them on. Clearly this is the most first world problem a climber could ever have, but hey ho - I am reviewing them after all
