The NINJA was the original unlined performance climbing slipper that got us thinking about thin cracks, thin edges, smeary routes and also specific training to get our foot and calf muscles strong. Use them for bouldering, thin faces, gym climbing and competitions. This year's NINJA has been updated with a slightly more rounded toe and a tensioned "T" strap across the top - which puts rubber on both sides of the crack and also is useful for "under-toeing" holds. Slip them on for an impromptu bouldering session or pull 'em out of your pack for making easy work of thin, "fingery" crack problems. Half mid sole balances your need for sensitivity on knobs with predictable fore-foot support for edging. New FS-Quattro Soles are unbelievably sticky and firm - providing a good grip on all types of rock. Keep your soles clean by brushing them prior to climbing with the handy SHOE TOOL (below). NINJA JRs have a velcro closure and is an excellent easy-in easy-out gym and crag shoe for your kids (tell us their running shoe size). Sold in UK sizes (UK9 = US10) - order 1/2 down from your street shoe size for a snug fit and all around climbing performance.
