Love these shoes for trails and asphault. Merrell's lacing system on these shoes, the Allout Rush, and the old trail gloves keep me coming back.

True to size. Almost like walking on cloud a cloud. Only thing I would change is the size of the laces. I found that, although they are adequate, I prefer laces a little longer so that I can double tie them.

I have owned almost all the Barefoot shoe line. I loved them because of the zero drop and the thin durable soles. I was not sure about the ALL OUT -Fuse. I have not worn a shoe with cushion in almost 4 years. I am a personal trainer and live in the gym and outdoors. I need a shoe that is able to do a wide range of activities and foot motions. The Fuse was able to tackle all that I have thrown at it thus far! More than happy with this purchase! In Merrell shoes I wear a size 8.5 in all other sneakers I wear a 9.

Colors not quite what I expected but close enough. One of the most comfortable running shoes I have ever purchased. Product size was about right as for the length, but the width only came in a medium and I have a wide foot.

Had to return this shoe and purchase a whole size smaller, but now that the sizing issue is worked out I am extremely content. The shoes are comfortable and ergonomic, lightweight, and good-looking. They also seem quite durable.
