Hello. I buy hundreds of products on line every year and I've never felt truly compelled to write a review, no matter how much I love the product. These shoes, however, more than deserve the effort on my part. They are without question the best fitting shoe I've ever had the pleasure of wearing. I have hard-to-fit feet - fallen arch on my right foot and other issues - and have found that I do best with barefoot shoes in general. Unfortunately, 5 Fingers and other shoes such as that are not really that great on rocky hiking trails. These amazing Proterra Sport shoes are quite the opposite. They allow for some cushioning and I haven't had a blister once! Not once! This is amazing for me as I typically hike with my feet protected and covered in Mole Skin. :) PLEASE PLEASE PLEASE never stop making this shoe. I absolutely adore them and have my husband hooked on the men's version now, too. Thanks again for making such great products.
