Having to admit the end of life as my 5.10 Free-runners lifespan was eased by the purchase of this newest 5.10 all round bouldering/parkouring/climbing approach-ish shoe. Like the Free-runner, these run half size small and to wear them the day after delivery meant stuffing balled socks into the toes overnight. In time (as in months), I hope the handcrafted construction molds to your foot like a custom shoe, which is when I came to LOVE the Free-runners. If there is a lot of hiking before a scramble, I'll pack these as there is less arch/cushion than typcial hikers. These make for a solid, supportive weight lifting shoe afterwhich they have the perfect stealthy stick for the rotating wall. In fact, my hands tire before my legs. Your feet will feel safe in them no matter what you encounter with the combined outer and stickiest rubber on the planet. With reflective strips, they're safe to pedal in and even pull off pairing them w/jeans and a t. If it helps purchase, Tom Cruise chose these as his climber for his last MI flick.
