Nice for keeping up the pace
"First Mach x experience and fit is good - not too wide even though I have half size up from what would normally get as 12. 5 seem to be like hens teeth and no heel slip. Use them in 7-10km faster runs. Find them a good tempo shoe although I think I am as fast in Superblast. Seem to be wearing well on the sole. Got for a good price so happy."
