I've worn my Berghaus Superlights a fair bit in the last three weeks (its been rather wet and the fields and footpath have been muddy and sodden) and they haven't leaked at all, which is nice.
Because I run every day my feet have been constantly wet for what seems an age. I have two pairs of off-road shoes but I just don't have enough time or the inclination to keep drying each pair every day so I just take the insoles out and dry them. The mesh at the toe areas are usually wet when I finish my run but by the morning the mesh has dried to just being damp so with dry inserts back in them I then run in almost dry shoes.
When the weather improves I'll switch to my 'new' Salomon Ulta X boots (the previous ones leaked and I sent them back) but I've decided if this pair leaks I'm just going to accept it and keep them. I just can't be bothered to go through the process of sending the shop photos, posting them off, and then waiting for a new pair to arrive. Except for the leaking issues I like these Salomon's boots a lot. I plan to use the same technique when I next hike, I'll take a spare pair of inserts plus an extra pair or two of socks with me, if the boots leak better to have half a wet boot than put my feet into a fully wet boot.
