John L.wrote a review of Sidi Trace Cycling Shoe - Men's on December 18, 2019
Familiarity: I've used it several times
Having worn size 45 Sidi Genius shoes for several years, I bought a pair of Sidi Trace size 45 expecting them to fit the same as the Genius shoes. Unfortunately they were slightly larger, allowing my foot to shift in the shoes and causing a great deal of pain in my feet. Changing to size 44.5 fixed the problem.
The picture shoes my feet after just three days (200 miles) of wearing the size 45 Trace.
