Bests & Worsts Reviews from Amazon

I saw the price was $25.99 and bought 2 pair! Wow, I thought. What a deal. I found these to feel, fit and look differently than my previous Superfeet purchased at nearly 2x the cost. Then I paid more attention to the reviews and discovered some reviewers identified their Superfeet as fake. I wonder if that is what I got and why the cost was so low. Should have paid better attention to the reviews before I made the purchase. This has impacted my trust in Amazon.
