I ran a Merrell/Subaru sponsored mud run and after test driving a Subaru, got a gift certificate for $110 in Merrell Money! (I don't think it is actually called "Merrell Money", but it should be.) Anyway, I've been slacklining for a few years now and have kept the sport strictly to the Spring/Summer/Fall seasons. This year, I want to set up a long line (~100') during a Pennsylvania snow storm (should the weather provide). The only problem is footwear. Although I've seen videos of people slacklining in high-on-the-ankle boots, I prefer freedom of movement in my ankles as I'm still new enough to wobble quite a bit. Sneakers are out for the immediate sock-soak. I wanted something for this application that would also have qualities fitting for moderately difficult trail hiking/climbing. I searched Merrell's site for a few weeks. What a selection. I had it narrowed down to either the Moab Waterproof or the Pulsate Waterproof. Another week went by and I still couldn't decide. Then... as if written in the stars... a NEW shoe popped up in my search. (Or had I missed it all this time?) The All Out Blaze Stretch Waterproof "Look at how low the sides are!" "Love the orange accents." "Huh, a speed hiking shoe. Never heard of "speed" hiking before." "Hmmm... stretch IS good for slacklining." "Oh wow... "cushioning that absorbs shock while firming up for confident take-offs"... what a way to describe a shoe. I want confident take-offs. I'd also like the job of describing gear for Merrell." This was the one. I received the shoes on a Friday when I returned from work. Although I was rushing to catch a train into the city with my bike, I took the time to try them on. Using a shoe horn, I slipped them on my feet and took a few steps around. My typically selective feet quickly fell in love (lust?) with this new footwear. They're like wearing sturdy slippers. Snug without restriction. Weight without bulk. Usually I try to break in shoes slower than this, but I kept them on, grabbed my bike and rode down to the train station. My lady and I rode bikes to the dinner that night. Rode on to a local bar to see a band. Danced a bit. Rode home. Although I felt no pain, I half-expected to find a blister at the end of the night. New footwear can be stiff and unforgiving to a lumpy foot. I found nothing. Since then I've worn these shoes for daily medium-active use. Always with wool socks. They've taken hikes through the Wissahickon Park. They've biked many miles and walked even more. They've slacklined. Wonderfully. They've stood up to a cold downpour. My feet stayed dry and relatively warm. The size after all of this has stayed true. Very little loosening of the structure which I appreciate. There is a small learning curve on the pull-lace tightening system. If pulled too tight, your foot with tell you. If too loose, you'll feel a bit of give. My give was around the sides but I was using them up on the slackline which puts a lot of pressure on the sides of the shoes I'm wearing. I mostly wear them a bit on the loose side and they snuggle my feet comfortably through the day. I couldn't be happier with the pick and I'm looking forward to the first snow storm slackline session. Have fun!
