The Nucleon GV is the mostly technically-minded shoe in our active/travel crossover category, but just about manages to qualify for casual use due to some understated colour options. The fit and materials however are aimed at making it a very capable trail shoe.
The list of branded technology crammed into the Nucleon GV is impressive; GoreTex lining for weather-proofing, Schoeller fabrics for breathability and longevity, and Vibram's latest 'Megagrip' sole unit for traction in all conditions.
GoreTex may not be everyone's choice for warmer weather travel, but there's no question it promotes confidence when the weather is a bit iffy. The Schoeller fabrics make for a really solid feel to the construction, and the combination of GoreTex and Schoeller has proven to be highly breathable.
The fabrics and construction also create a surprisingly supportive shoe, given its relatively low weight of 325 grams (per size 8 shoe). The fit helps here, as it is fairly narrow and offers easy foot placements. The flip side of this is that the Nucleon GV may be a little too unforgiving (in stiffness and close fit) for all day wear, on and off the trail.
The Vibram Megagrip sole is the star of the show however, and is seriously versatile. The rubber compound has proven sticky in wet and dry conditions, and the lug pattern is more aggressive than most in this category, while still maintaining a low profile look, which will help you blend in when not on the hill!
The rubber is also more durable than most, which will count for a lot when street-pounding and sight-seeing is factored in.
Great value considering the amount of tech involved, and if you're a fan of a relatively stiff shoe, the Nucleon GV could become your go-to travel footwear. If you prefer a softer, post-hike shoe, the Nucleon GV is light enough to pack as an extra option.
