These Vibram shoes are made poorly.  The sole on the toes was de-laminated,  which means that the adhesion process used to laminate the synthetic rubber sole to the upper part of the shoe was sorely lacking, and it reveals that only the outer edges of the sole are used to adhere, rather than the complete sole, which should be bonded to the fabric.  Too bad, I like the concept but abhor the workmanship.
The seller did refund for the merchandise and shipping promptly - thanks!
