The Berghaus Explorer Trek Plus GTX is huge seller that offers value, reliable performance, waterproof protetcion and grip on mid level trails and hikes. The optistud sole in particular sticks to the trails like jam to a warm scone.
Aimed at those looking for a waterproof boot for fell walking in the dales and hikers on long distance paths with reasonable conditions underfoot, the Explorer Trek Plus GTX has all the features you'll need at a decent price and the Ortholite insole provides great all day cushioning.
Things tend to unravel a bit when conditions get a little steeper as the boot lacks a bit of torsional stiffness and the soft upper is prone to giving way when side-hilling on steeper ground. The lacing system is decidedly old school and the heel cup is quite wide and soft. Looks-wise, it's a touch old school when compared with some more modern offerings but that may well be the key to its success - a conservative, comfortable and reliable performer if not pushed too far beyond its comfort zone.
If you are looking for an all day boot to use on everyday rambles and trails and aren't interested in flashy looks or going into steeper and more technical terrain, the Berghaus Explorer Trek Plus GTX could well be exactly what you're looking for.
