Okay, we're with Christian Allen of the
0:03
Nike ACG or the racing department and
0:06
Christian's going to give us a little
0:08
introduction to the ACG Ultrafly 2 and
0:14
we went running earlier today in them
0:16
and I really enjoyed my first run.
0:18
Really agile, fun shoe, lots of
0:20
cushioning and Christian is super
0:23
versatile. He not only ran a 210
0:26
marathon this year, but he's also the US
0:29
vertical K champion. Okay, Christian,
0:31
tell us about the shoe and and what
0:34
you're thinking.
0:35
Yeah, it's fantastic shoe. I'm super
0:37
happy that ACG is adding this to our
0:39
quiver of racing shoes. Um, it's 289 g
0:43
out of men's size 10. We got a 39 to 31
0:46
mm uh stack offsets. Um, and then on top
0:51
of that, the shoe comes with a full
0:53
Vebram Mega Grip. Uh, super grippy,
0:56
really not much slippage. We tested it
0:57
out here on the slippery wet rocks here
1:00
in Shamine. Uh, and it's a carbon plate
1:04
uh, in there as well. So, you kind of
1:06
got just the typical carbon plate to add
1:08
to some of that stiff rigidity to help
1:10
with fatigue over time in the MTP joint.
1:14
So, you're not having to expend as much
1:16
energy or force. But it's a phenomenal
1:19
shoe.
1:20
And I see there's kind of a web here
1:22
that kind of stabilizes.
1:24
We've got Zumx. I really enjoyed my run
1:27
in them. I was surprised. Uh they're
1:29
quite rigid, but they run like a
1:31
flexible shoe. So I think the carbon
1:33
plate they said is maybe split down the
1:36
middle. Very nice shoe. And so what
1:38
what's next in your year, Christian?
1:41
I'm I'm going to finish off the year
1:42
with a vertical champions at Worlds uh
1:45
in September out in Camp Frank. And then
1:47
I will continue at the Golden Trail
1:49
final in Italy. Um, and maybe I'll have
1:51
a few small world uh or just trail races
1:54
after that. But then I'll gear up for
1:56
the US marathon champs in December at
1:58
CIM.
1:59
Excellent. What versatility. Thank you
2:01
very much for for speaking with Roadt
2:04
Trail Run and for joining the run. It
2:06
was great.
2:07
It was a pleasure. Thank you. Okay.
