I have used these shoes for a 50k trail race and a 100 mile trail race, as well as daily training. They are fantastic in almost all aspects. The grip is amazing on all types of terrain. They drain well and dry quickly. They feel great on my feet and strike a good balance between great cushioning and responsiveness over long distances. However, they cause severe blisters on both heels. The material that VJ has used here is a little on the sticky side and this creates a lot of friction in the heel area. I love everything else about the shoe, so I put multiple layers of KT tape on my heels just to be able to run in them. VJ, if you can fix this you will have 5 star shoes for sure, something that can be used anywhere and any distance.
Great shoe. I went down a 1/2 size from my normal shoe size. The grip is awesome and the midsole was excellent for about 90 miles. The midsole felt flat and did not filter out sharp rocks at about 90 miles. I think if VJ designed an insole like Inov 8 boomerang insole it would make these shoes a 5 star for me. Overall I love the shoe and will probably buy another pair .
