Wow, blast from the past, I'd forgotten all about this, since then I have:-
tried several flat pedals, tried strapless toe clips, traditional clips, Powergrips, Holdfast Straps and SPD pedals and shoes.
I now have pinned platform pedals on all bikes, recently got some Superstar Nano ones for the road bike. If I like them enough then they'll replace my cheapo Wellgo BMX style clunkers on the other bikes.
I did buy the 5/10 Impact Low shoes and they are seriously grippy and very comfy. But they are large, pretty heavy, a little hot in warm weather and absorb an incredible amount of water, and take an age to dry, if they get a soaking.
So I'm toying with the idea of using another 5/10 design and some of their Freerunning models look the part. Much lighter, drain/dry well and the same super grippy sole. I think the Impact Lows are just too much shoe for on road riding though they have covered a lot of miles, about 7k at the last count.
For the laces I just do a double bow and then tuck all ends into the laces themselves, they've never come loose yet.
