The Ultramite Trainer




Speedland has unveiled GS:TAM, the third iteration of their ultra-marathon distance — 50K and beyond — trail running shoes. Speedland is known for the revolutionary design of their shoes, that combine cutting-edge technology with premium materials for optimal performance and comfort. The GS:TAM was designed with Speedland athlete Dylan Bowman, top American professional trail and ultrarunner, who has made his home the trails of Mt. Tamalpais in Marin County for which the shoe is named.

Like its predecessors, GS:PDX and GS:HSV, GS:TAM has been crafted with unrivaled components. It picks up where these previous models left off, with the next level in industry leading technology. GS:TAM is Speedland’s first max cushioned shoe. With a full 37/30 mm midsole stack, it provides high energy return without sacrificing compression, increasing the lifespan of the shoe.


The GS:TAM has a unique beaded Pebax outer midsole and removable midsole section. Michelin Fiber Lite outsole ensures a sticky grip over any surface. An optional Carbitex GearFlex carbon fiber plate sold separately (compatible with all Speedland models) adds propulsion and protection on race day. An integrated knit bootie with a PerformFit™ Wrap activated by a double-dial BOA® Fit System that adjusts incrementally, both forward and backwards, for zonal control and a customized, secure fit.

While all the features are extremely technical, what’s most distinctive is how these components come together to create an eye-popping design of a trainer. Fashion loves to adopt a technical shoe, and the combination of the orange mesh upper with perforated wrap straps, white plush midsole, green tread, and white dual BOA® dials are sure to make this a hot and coveted street shoe as well.



The GS:TAM is available for pre-order on for $275 with an expected delivery date of March 2023. The Carbitex GearFlex carbon fiber plate is sold separately for $35. Speedland footwear has a direct charitable tie back to its athletes with a portion of all profits going directly to Bowman’s non-profit of choice, Footprints Running.
