Take the wildly popular Zen and– upgrade the EVA midsole with an injected model for longer life. Upgrade the Vibram® sole to the Spyder II, which offers great stick, but won't pick up pebbles and gravel. Upgrade the leather along the side with PU-injected reinforcing, improving abrasion resistance. Upgrade the fit with SCARPA's Sock-Fit DV system, giving them the feel of a running shoe, but the sensitivity of an approach shoe. That's our theme for the Zen pro this year _ upgrade. Try on a pair and feel it.
