I've found (on other bikes never run clips on my fixed wheel) that my pedal choice and shoe make a bike diffrence to feet slipping out. I am sure you know this but work tring out some diffrent pedals, maybe a bit more agressive. Not trying ot preach as like I said never run clips and straps on a fixed wheel only on my mbt years ago but agressive pedals can be good.
