I'm a long time clipless rider. I've made the switch to platforms, however, on my fatbike and commuter. Both have platforms with significant pins (shimano saint on the fatbike, generic similar on the commuter). For me, the "trick" to making pedaling platforms feel similar to clipless is all about the shoes. Below 25 degrees on the fatbike I wear a soft soled Salomon boot (image number 2 below). The soft sole "absorbs" the pins. Above 25 with my fatbike and commuter I ride a pair of Five Ten Freeriders (image number 1 below). The Freeriders have a somewhat sticky sole with very shallow round nubs that the pins stick between (image number 3). The combination of pins and soft and/or sticky sole means no slippage. In fact, with the Five Tens I can's reposition my feet on the pedals without lifting them off a bit. I feel as if I am clipped in.
