Speedland - GS:TAM

The GS:TAM is the ultimate trail equipment for long distances. Precision fit is paired with maximum comfort and responsiveness to propel you through the mountains faster.

This is Speedland's 3rd model--a.k.a a commission at Speedland--built with more stack to meet the needs of pro trail ultrarunner, Dylan Bowman. He asked for a shoe that will go the distance for long days--and for days--and the GS:TAM meets those demands.   

The Story behind the GS:TAM

Named for Mt. Tamalpais, the GS:TAM was designed and perfected with Speedland athlete Dylan Bowman.

Features include:

• 100% beaded Pebax® external midsole
• Proprietary drop-in midsole blend containing Pebax® elastomer (removable)
