<!-- raw HTML omitted -->The styling is a real departure for the company and a bit too marshmallow-y for my tastes. I do love the orange nylon FlexPlate sandwiched between the midsoles. Merrell says it “delivers 100 percent more energy return than the leading hiking boot.” <!-- raw HTML omitted --><!-- raw HTML omitted -->

<!-- raw HTML omitted -->For testing, I’d swap back and forth between my trusty Adidas trail runners and new Merrells over a total of 40km (about 25 miles) — I couldn’t wait to get back to the FlexPlate each time.<!-- raw HTML omitted -->

<!-- raw HTML omitted -->The FlexPlate prevents things from feeling squishy while also providing a slight but noticeable boost to each step. That propulsion makes the SpeedARC feel lighter than its 14.35 ounce (almost 407g) weight would suggest.<!-- raw HTML omitted -->

<!-- raw HTML omitted -->The dual-BOA system is satisfyingly clicky and cinches the shoe tight through a series of turns. The fit is supremely comfortable and secure with the pressure evenly distributed around the foot.<!-- raw HTML omitted --><!-- raw HTML omitted -->

<!-- raw HTML omitted -->The heal-to-toe stack height of 38-30mm and rubber treaded outsole with moderate 4mm lugs combined to diminish ground feel. The height also made me feel a little unstable when moving quickly over technical obstacles or on steep sloping declines. <!-- raw HTML omitted --><!-- raw HTML omitted -->

<!-- raw HTML omitted -->The upper is covered in a stretchy, breathable, and abrasion-resistant knit fabric reinforced with Kevlar. This is a dry-weather shoe not to be worn in the mud or rain.<!-- raw HTML omitted -->

<!-- raw HTML omitted -->The gaps between the nitrogen-infused midsoles are going to collect mud, dirt, and debris over time.<!-- raw HTML omitted --><!-- raw HTML omitted -->

<!-- raw HTML omitted -->I’m not a fan of the raised internal stitching used to secure the lowest tab on the BOA cinch system. It protrudes enough that it began to rub on the top of my left foot, just behind the pinkie toe. I was able to alleviate this blister-maker by cinching the shoe more tightly than I wanted. I did not have a similar issue on my right foot which is ever-so-slightly smaller.<!-- raw HTML omitted -->

<!-- raw HTML omitted -->Who is the Merrell SpeedARC Surge BOA for? Anyone looking for a breathable, fair-weather shoe that reduces foot-fatigue on long hikes over terrain that’s not overly technical.<!-- raw HTML omitted -->
