I have had alot of plantar issues and the pure flow has worked well for me for a couple of years. Even ran rim 2 rim Grand Canyon in them last year. Looking for a trail alternative mostly for traction purposes. I will try the new version of pure grit (I did not like the first version) but are there others? I think the features that make these work so well for me ... light but has cushion with plenty of flexibility. Most trail shoes are rigid or hard on the sole. With the cushion I have not had issues where I thought I needed anything firmer or a rock plate.
