Hi again Jean, as i mentioned earlier, the fit of my ME:sh shoes is perfect.maybe because of the material used or because of their flat shape,were untied with some regularity during the race,so i thought that they were not necessary for the fit.so,i decided not to use them anymore.iam a fan of minimalist solutions ,and aesthetically my ME:sh shoes i like them more laceless.Maybe for being the first owner of a ME:sh shoes in Spain,i have become in ME:sh "ambassador"so i showed the ME:sh to many runners in differents events,but i always did it using laces.
Cheers,Rafa
