don‘t know about casual wear all day, but love to run in them no matter the paceAfter breaking them in I can’t say enough good things about the Ultraflys. Great for running. Great for casual wear. Great for walking all day. Will look for another pair after I beat this orange pair into the ground.
super smooth transition and very stable, got 2 pairs now.Did they fix the seam in the heel? The original had one running right down the middle, and it gave me the quickest blister I've ever had, right at the base of the Achilles.don‘t know about casual wear all day, but love to run in them no matter the pacesuper smooth transition and very stable, got 2 pairs now.
never had the first ultraflys but the acg ultraflys have no seam internally. heelcounter is really sturdy and stable which i hope the new zegamas will also get. the zegama 2s were too flimsy for me in that area.Did they fix the seam in the heel?

Huh, sure enough. Maybe it was from the seam down the outside of the heel? Whatever it was it didn't feel great on the one I got.Original Ultraflys also don’t have a seam down the inside heel.

unfortunately compared to zegama 2s the cw are really monotone/boring.

Hearing this is the Kiger Flynew acg race shoe prototype seen during the black canyon ultras, worn by 2nd place acg athlete anthony costales. looks like an evolution of the acg ultrafly.

has been spotted again yesterday at the gorge falls 30k on some acg athletes. would make sense to be a kiger since it's supposed to have no plate and the kiger is nike's technical trail shoe.Hearing this is the Kiger Fly![]()
This thing has incredible temperature regulation. Perfect for runs in the 30s.$53.97 ACG Wolf Tree Crewneck Sweatshirt
