  • Surprisingly great shoe for walking on concrete in downtown Chicago

I live in downtown Chicago and need a shoe with great support and padding as I walk a few miles every day on concrete sidewalks. When I first got this shoe, I was a little disappointed as I did NOT want a barefoot shoe and was looking for a straight trail running shoe. After a few walkabouts, I have totally changed my mind about barefoot shoes. This shoe provides amazing support, is very soft and light, and provides the perfect amount of cushion. The support comes from the actual construction of the shoe and how it wraps around my foot rather than just putting a bump in the insole the way traditional tennis shoes do. If I want more support, I just tighten the laces. The shoe breathes great and I'm not getting the foot fatigue feeling that I normally did after a 5 mile hike over concrete sidewalks. Nice shoe. I'll be getting it again.

The web images make these "molten lava" shoes appear to be a combination of red, red-orange, orange, and yellow colors. When I received the product, I discovered that they're actually lime green! Green and red make a very bizarre clash of colors, not complimentary like red and yellow. I would suggest to Merrill that they check the color calibration of their image work flow to be sure that the gamut of their images is sufficient to render the shoes online, and also test with both Mac and PC through various browsers. I would suggest to fellow customers that they make note of the lime green soles and lime green lines on the sides before buying.
