Have been using the Adidas Adizero Adios 3 as the racing flat (with Lock Laces, sockless) for draft-legal sprint races. But I have found them to be a little hard to put on in T2; not sure the exact reason, but could be because the position of the loop on the tongue is quite low. Daily training shoes are Saucony Kinvara and Zealot.

Looking for some suggestions in racing flats (neutral) that are easy for fast T2 in barefoot.
