Editor’s Choice – Urban Climber

“The Boostic is an all-around outstanding shoe. It has everything I like: a simple heel, powerful downturned toe (but not too intense), Velcro closures, leather uppers, precise edging, and great rubber…This shoe should make a stellar addition to many climbers’ arsenal of boots.” - Urban Climber


Five Star Review – Rock & Ice

“A go-to slipper for hard routes and boulder problems. With Boostic, the shoe designer Heinz Mariacher has dialed in that fine balance between support and sensitivity. The Boostic is on the softer side , yet delivers a surprising  of toe power on steep angles. Unlike some slippers, the Boostics are easy to get into”. - Andrew Busharat – Rock & Ice 



“Boostic: a great product! Precise shoe perfectly adapting to the foot. It offers optimum sensitivity even on small edges. The Velcro closure guarantees a snug fit and the best precisione. Details make the difference even on the wall!" - Alessandro Baù
