Five Ten NIAD Moccasym Climbing Shoes

The Men’s Five Ten NIAD Moccasym Climbing Shoe is a slip-on bouldering, sport, and trad shoe renowned for its comfort, sensitivity, and sticky rubber performance[2]. It features a flat-lasted profile and unlined, split-grain leather uppers for a customizable, breathable fit that molds to your foot over time, delivering a glove-like sensation[2][3]. The extended toe rubber patch significantly enhances toe-hooking ability and protects the shoe during hand crack jamming, while the low-volume toe box and neutral last make it a natural choice for crack climbers and those who prioritize comfort on long routes[1].

A full-length, flexible 0.5mm midsole and thick 4.2mm Stealth C4 rubber sole provide just the right blend of sensitivity, edging power, and friction for smearing, jamming, and edging on a variety of terrain[2][3]. The heel rand has been updated to a two-piece design for a better fit and increased tension in the heel cup[3]. Weighing in at 9.1 oz (size 10.5), these shoes are built for all-day comfort and are especially suited for crack climbing, slab, and long days in the gym where easy on-off and breathability are valued[2][3]. Note: This model runs small—size up for the best fit[2].

**Most Suited For**

The NIAD Moccasym is ideal for climbers seeking a sensitive, sticky, and comfortable slipper that excels on cracks, slabs, and vertical terrain. Its all-day comfort and easy on-off make it a favorite for gym climbers and those tackling long trad routes. While not aggressively downturned, the extended toe rubber and improved heel rand open up new possibilities for modern bouldering and gym moves, but it remains a specialty shoe for crack and comfort-focused climbers[1][2][3].
