      great shoes for price

      If you’re looking for a shoe that prioritizes support and comfort, this is it. The dual-density midsole feels secure and responsive, and the heel lock is one of the best I've experienced. I’ve worn these for everything from urban exploring to rocky paths, and they hold up beautifully. Sizing tip: I found them true to size, but the toe box is nicely roomy for those who need a bit more space for toe splay."

      Narrow and off-color

      Color did not match well to on screen color. But more important, I always order Merrell’s 1/2 size up and these were very narrow fit. Had to return.

      Very pleasantly surprised!!

      At over 70 I don't trail run, but prefer the rubberized indoor-track at my local athletic club instead. I took a chance on these Merrell's just as knock-around shoes I liked the color of. Wow! What a comfortable shoe! I definitely prefer cushioned shoes in my old age and these more than fill the bill. Super comfortable and good looking at the same time (mine are white with orange highlights). Overall, I'm very pleasantly surprised with these shoes and wear them frequently!!

      Vegas Baby!

      We went to Vegas and enjoyed wandering Las Vegas Blvd. Did a lot of walking! The shoes have a great arch lift to them and handled hiking at Hoover Dam as well!

      Not my favorite

      Stylish, but not supportive for distance walking. The extra cushioning in the midsole comprises stability.

      Another gem from MERRELL

      Great semi trail running shoe, love the fit and practicality. Firm enough not squishy but also provides cushioning and energy return

      ProMorph

      I am a hospital security officer for a multi story hospital, spending 70% of my time walking on concrete I need a dependable shoe with good support, breathable & cushion. Over the years I’ve tried just about every brand out there & these ProMorph shoes are some of the best shoes I’ve found if not the best. At the end of my shift my feet are not sweating or sore. Also im 6’1” & 290 lbs thank Merrell you hit it out of the park with these. Now if you could make a boot with this cushion sole that would be great
