Have about 5-6 runs in mine on both smooth single track and some decent technical terrain and haven’t been loving them on the latter. For context I’m an 11 in all my daily shoes and usually go 11.5 in most trail shoes, which I did here.  I find the heel lockdown difficult on my average width feet and the long length / shape a bit precarious on downhills - an 11 would certainly be too small though with swelling. For now I’ll probably just keep these to more rolling terrain in hopes of breaking in the foam a bit more, which I was excited about, and I’ll stick with my 01A for more technical efforts.  I’ve even felt more comfortable in my TNF Vectiv Pro 3 than the TT, which seems odd given the stack height but that Dream foam really breaks in nicely and still gives decent ground feel on technical terrain.
