The more you run, the more you tend to change your gait, moving towards the front (falling) running technique. This usually mean the runner changing into shoes with less support and less drop. In swimrun most racers use shoes carrying dubs, leaving the selection of shoes to buy from much narrower.
Not having that many options might influence some to go for new and untested ones. Here, one thing to bear in mind in, as shown by the research below, is that going for the minimalist shoe will increase the load on the Achilles tendon, and most likely also the risk of pulling an injury. So, change the shoes yes, but perhaps not in the middle of the season and not straight-up directly from a steady one to a minimalist version with low drop.
