I've been battling with tarsal tunnel syndrome for a few months. My podiatrist gave me the green light to run again but said I should do so in a " low collared shoe". I'd been road running in Asics Gel Nimbus 14 and trail running in the Salomon Speed Cross 3 ( the likely culprit for the TTS, according to the Doc). Is anyone aware of what shoes (road and trail) are low collared. I don't really think the Nimbus are a problem but I'm willing to explore options. I like the Kinvara but would prefer more cushioning. Thanks for any help. Peace.
