Do it all in a day without changing shoes. If you're like most of us, you like to mix up your climbing action. Five Ten's multipurpose T-Rock is the spice of life across faces, smears and cracks. The proprietary ST rubber outsoles in Five Ten shoes have a reputation for unsurpassed friction performance, but no shoe works without a slip better than those properly shod in ST C4, the most tricked-out, stickiest sole you can edge on any surface. Like other Five Ten shoes, the T-Rock features a patented side exit heel seam that eliminates the hot spots typically associated with shoe stitching.Features:Padded split tongue beneath a lace-up closure Synthetic Nubuck upper Anasazi last ST C4 sole for optimal friction Manufactured in the USA
