I recently went on a trek on the foothills of the himalayas. "Har ki doon" specifically. I used a Quechua shoe for this trek. Although this did keep my feet warm and dry, the comfort level left much to be desired. So which are the other brands which provide good trekking shoes? Please consider worldwide availability while providing the answers. Also, lets just consider the quality, comfort and features and not the pricing of the shoes. Request you guys to help me out on this.
