The 1st 10 miler in suede Xeroshoes was a failure.  The sole didn't cause any blistering, but the sides were still blistered.  The heel area with its gimmicky side lugs is just too narrow.  The toe plug still caused well & truly blisters again.  The suede didn't break away from the laces, but it became quite hard in the toe area.

Target insoles lasted around 50 miles. It was time to go when large pieces broke off under the toes.  They were pretty cushioning, but their thickness may have aggravated the toe plug issues.  The last of the suede scraps went in.

Toe plug blisters remane the biggest problem, since the rubber under the toes is much heavier than a commercial shoe.  Would say commercial shoes have a toe drop out of necessity to lighten the toe area.  Steep footing on hills until the lion is pushing more on the strings than the soles is another problem.  A complete shoe upper is the result of spreading the forces on the laces over a wider area.
