When I plan for a race, and even training runs, I wear shoes to match the intended pace and terrain. This means I sometimes wear two different type of shoes running the same route on different days. For instance I love to wear my Saucony Rides on days I want to work on faster downhill running on the Mt. Wilson Toll Rd. On the same course I’ll wear my Mizuno Kazan, Montrail Bajada, or Brooks Cascadia on days I need better grip to work on speed hiking or faster uphill running. On streets I’ll either wear Mizuno Wave Sayonara or Saucony Triumphs depending on distance/time-on-feet and pace. I’ll even wear Sayonaras on trails for speed workouts (Brown Mt., El Prieto, Sam Merrell, Cheseboro, and Griffith Park). So, all this to say you should be varying your shoe choice. Shoe variation improves strength, helps with injury prevention, provides specific feel for different surfaces, and extends the life of a shoe. At the very least have a second pair that is the opposite of your regular trainer. If you run in a supported shoe, keep a second pair that is more flexible or less cushioned or a lower ramp height for recovery runs or for speed work. It will activate, stretch, and strengthen muscles, tendons, and joints that normally wouldn’t be in a more supported shoe.

Running in minimalist or barefoot shoes? Try a firmer shoe for racing so the shoe can help with biomechanical efficiency. Softer/minimalist shoes use more muscles and more joint movement from foot plant to toe-off in slower paces.
What you’re all dying to find out, what shoe did I use for Sean O’Brien 50 mile race a couple of weeks ago? I wore the Mizuno Kazan. Same shoe choice as Bulldog 50k. Picked this shoe mostly for the outsole. I wore the Montrail Bajada and Saucony Rides on all trail runs leading up to the race. I knew I needed a shoe with a firmer and cushioned heel for the downhill running, but also having some flex in the forefoot for steeper climbs. Cushioning would also be key because of the rocky terrain and the walking I would do at some part of the race. The Kazan only became an option when I wore it on my last training run up Mt. Lowe. Although it wasn’t as cushioned as the other shoes, it provided the best grip. I would sacrifice comfort in the Kazan (especially when running downhill), but the shoe’s flex through the forefoot provided better options overall for faster running.
