Customer Reviews
It’s rare that a shoe can be a 10/10 in every department — the GS: TAM is one of the few.
It rides comfortable AND responsive; it grips to the trail like a mountain bike tire; it fits to the foot like a glove and the adjustability is clutch yet again.
I paired mine with the carbon plate for the extra power…wow, it’s like someone created a 4x4 Ferrari for your feet.
I can’t fault this shoe. Not even a little bit. Total game changer for me. Can’t wait to put another few hundred miles on it.

Responsive, protective, durable, stylish... The perfect recipe. I got 600+ miles on my first pair. A premium product and a great value!
