Short Version: I need a zero or 4mm drop shoe with soft interior, no seams etc that is good for sockless running.

Long Version: I bought a pair of Zoot TT shoes probably 5 years ago when I decided to go sockless running for shorter distance triathlons and loved them. The upper has no seams so no blisters etc. and that worked very well for me. Recently, I switched to Altras (Torin and Escalante) for my everyday running and love the no drop shoes--work much better for me than Nikes, Asics etc. that had much more drop.

I am due for some new tri-only shoes. I will really only use these shoes for short distance tris so I expect them to last years. But there is no way I could run sockless with the Altra's. The Escalante, which is my favorite shoe, is very scratchy on the inside even with socks. There are still some older version Zoot TT's that are still available on certain websites, but those shoes are kinda dinosaurs now and I have gotten away from the 8 mm drop.

Any recommendations for shoes with little or no drop that have a sock-like interior that works well for sockless running (without having to condition my feet to sockless running)??
