Who should not buy the Aku Slope GTX

Take the Aku Slope GTX off your choice list if you are after hiking boots suitable for grade 3 scrambles. An expert reviewer said that he would not be confident wearing the boots for that. Also, wide-footed wearers may not be comfortable with the width dimension of the shoe's forefoot section. They are better off with the Oboz Sawtooth II Mid.

The Aku Slope GTX uses durable Italian suede leather for its upper. It is combined with an Air 8000 fabric (1.6 mm) which makes the boot lightweight and extra breathable. Underneath these materials is a Gore-Tex Performance Comfort lining which gives a modest amount of insulation, prevents water intrusion, and expels moisture out.
