Having only worn these shoes twice, I noticed that the edges of the tongues were frayed in both shoes, exposing the white padding in the tongues. The abrasion is in the same places on the tongues of both shoes and they line up perfectly with the stitching near the lace holes. If it hadn't been for this issue I would have given the shoes 5 stars on all counts as they are light weight, comfortable and great. fit. I contacted Mountain Warehouse so wait what they say.
