Taking a break from ultra running in 2022 to try to reset, at age 36, some PR's I set in the shorter distances when I was 18-25. Looking for a recommendation for new track spikes that might be similar to the Nike Kennedy's and Ventulus from circa 2000-2005. I inherited pairs of the Kennedy's and Ventulus from friends who stopped running after college and I want to preserve those for the few track races I'll do, so I'm looking for a moderately priced distance spike to use for hard efforts in training every so often to keep my legs acclimated to spikes. Thanks!
