have North Face adrenaline both in Hiking boot, and low style. Found out that style is discontinued...Is this style similar? I like the ridge in the insole part of the boot, light weight of boot.

Dave Dean,I am familiar with the Adrenaline you have been using. Compared to the Vindicator they are pretty similar in styling and with features.Waterproofing: Both have Gortex Lacing: This style has tabs instead of eyelets. You will not notice a difference in this category. Insole: The Vindicator uses what TNF calls Norhodic footbed. It should be the same one you have in your Adrenaline. Take a look at http://www2.thenorthface.com/ap/technologies/technologies-FO18.htmlSole: Uses a more aggressive (larger lugs) Vibram sole. If anything I see this as an upgrade.Shank: Both shoes have a synthetic shank for added rigidity.Fit: I have not tried the Vindicator on. From pictures it does look more rugged all the way around. Possible a little wider and higher volume. Bottom line: It looks very similar and the Adrenaline sounds like it worked very well for you. Pick up a pair, try them out, and post a review.Mahalo, Sumo
