So sorry that this sneaker, a favorite of mine since I was a teenager, raised blisters due to a bulky seam that is hidden in the toe of the right shoe.  Unfortunately, there seems to be no way to correct the problem.  I counted on these shoes to be my 'go-to' footwear at Disney.  Though broken in prior to our trip, the seam created painful problems!  I certainly hope future sneakers are made with more care than this pair.
