Query: Good buy at $50

Bought these on a 1/2 price sale. The best looking $50 shoe I've ever bought. The sizing is accurate, and the finish is good.However, they are not worth the suggested retail of $100. The quarter lining is non breathable plastic that gets hot, the composite soles generate static electricity as you walk, and the sides cut into my ankle (less so now that they are broken in).
