Chapter 1: “The Case 0f the Baffling Sole.” Using extraordinary powers of observation and logic, Shoelock Holmes began to unravel the mystery of Keep, a new L.A.-based company rumored to crank out adorable, comfy, well-priced kicks. Holmes was not entirely convinced that was possible. She puffed on her pipe (just for effect) and considered the evidence. Exhibit A: Benten, a boat shoe (in green, gray and yellow, natural, or black) with molded gum soles (for fine sea legs). Exhibit B: Ramos, a classic canvas midtop with gingham, check, plaid, or seersucker shirt fabric detailing and lightly padded ankles. Exhibit C: Duke, an updated tennis sneak with pics of feathers or braided lace screen-printed on the toes. Holmes called her trusty sidekick to go try on a pair — or three. Watson confirmed that Keep shoes were charming (look at the spring colors!), snug (feel the foot cushions!), and reasonable (less than $100!). The Keep shoe: On the pavement, it’s fantastic. On the docks, it’s genius. On the grass, it’s incredible. On the whole, it’s elementary.
