Under Armour has completely resigned the Valsetz boot from top to bottom and call it the Valsetz RTS (Redesigned Tactical Shoe).
The tread has been changed and the instep has been upgraded for Fast rope operations. The replaced the stitching in the upper with a welded reinforcement. Additionally, the entire shoe is DWR coated. The top incorporates the Clutch Fit technology from their football shoes. This fit works much like taped ankles without the additional weight.
All told, it’s 2 ounces lighter than the precious model. The Valsetz will continue to be available for some time, but the RTS models are coming July 2014 from ww.underarmour.com in Tan, Black and Coyote.
