Lowa Monowrap Constructed Model: I'm Peter from Lowa Boots, and I'd like to show you one of our lightweight monowrap construction products. It's built with a PU-injected frame that comes out from the midsole to provide support for the upper. PU under the foot for shock absorption and rebound. It's a great long-lasting, comfortable material. Great for walking on all day. Nice soft flex on these boots, and a nice rugged, durable outsole, with a great heel built in for downhill decents. This model is the Vento Mid which has a split leather and open mesh construction. Nice and cool on a hot summer day. Great for desert hiking. Great for hiking in warm climates that are humid, and allow the boot to ventilate. Boot like the ALT with the monowrap construction frame will provide great stability and support, even when you're carry a light-to-medium weight pack. I'm Peter from Lowa Boots, and this is one of our ALT models with the monowrap construction.
