Unfortunately, they developed a hole in the upper mesh part of the shoe on the inside,just before where the natural bend in your foot happens.  This is with very minimal usage as they were bought for Track(last 2 meets). The opposite shoe showed the same kind of &#34;blow-out&#34; starting to happen in the same spot - not a typical place for shoes to show wear...especially when the shoe is under 3 months old, not worn for anything except Track,bought for the last 2 meets, and my son missed the last two meets b/c of illness.....  I wouldn't recommend at all this shoe.
