I have the Adidas Adistar and they are worth every penny. They ventilate so no fogging up and have adjustable arms so fit is excellent. Its my second pair (not poor quality, just use them so much) and got them from Vision 3k who had best price and great service. Thinking I would save money, when first pair died I bought several cheaper pairs which fogged up, didn't fit and weren't adjustable, etc. etc. It was false economy because they were a complete waste of money.
