I'm a runner in my early 50's who usually runs 5-10 km a couple of times per week at around 4:40 - 4:50 min/km pace. I was looking for a light, responsive shoe with a moderate heel drop because zero drop soles are hard on my ageing achilles. The Ravennas ticked all the boxes. They fitted my foot really well. I was really happy with them until the upper split on my 5th run, which was in the wet. I thought Brooks shoes were more durable than that. Big thumbs up to Amazon who have replaced the shoes. I hope the new ones don't have the same fault.
