Thanks to the generous people at Mizuno, I have been running in the Wave Paradox stability trainers. I also wear custom made orthotic insoles, which I have placed inside the trainers. The trainers are the most light-weight stability shoes I have ever owned (and I have tried a lot!) because of that, I imagine they would be good for shorter distance racing. They are comfortable and provide support, but I don’t see myself wearing them for anything longer than a 10 miler or half marathon. However, that could change the more I wear them!
