I play a lot of sport, and wear almost exclusively Asics trainers (sneakers if you like the other kind of English) to do so. In fact I only wear one pair of trainers, to the gym, to classes and for netball - which might be a mistake. One pair of trainers used to make my toes go dead sometimes, usually when running. A woman I was playing netball with at the time re-laced my trainers and that stopped the problem. My new trainers are giving me the same problem, and luckily I was able to dig out those old ones and copy the lacing - so here it is for posterity (and for next time I have this problem and can't remember how to do it).
I'm not sure why this works for me, I have a high instep so perhaps it relieves pressure on a key point? Anyway, if this works for you, or if you have any tips - leave a comment!
