Thanks. I'm not paranoid about the QC from Meermin and do find them a great value for money.
I've got 6 pairs so far. Some have uneven stitching, or uneven tongues, etc and I'm fine with that.
I'm just concerned about the durability and comfort. I checked my other 5 pairs of Meermins and the heel and upper sole were even, except for this pair.
Hence, my concern.
I thought about topying/vibraming the upper sole to thicken it, making it even. But this pair...
