La Sportiva's Trango TRK Tower boots offer precise footing over varied terrain from a mid volume last. They're most at home on easy to moderate mountain trails. Thermal processing allows the upper to be seamlessly formed to the sole which means there's less likelihood of it coming apart and the scratch-proof polyester mesh upper has TPU overlays which help form the boot to the foot on lacing up. A fabric '3D Flex' area just above the ankle bone allows the ankle to move for better comfort and dexterity but the Trango TRK doesn't feel quite as supportive as some in that area - it's down to personal preference as to whether that suits you or not.
The midsole and insoles lack cushioning so you get a fair bit of trail feel through the bottom of the boots, they're also geared towards those who prefer a nuetral feel underfoot rather than a pronounced roll.
Overall our experience with the Trango TRK GTX was underwhelming but some of the negativity might well be down to personal preference, the addition of aftermarket insoles would help iron out some of the problems.
