This decidedly Technical
shoe is the product of legendary Austrian climber and rock shoe designer, Heinz Mariacher
, who was previously responsible for a range of superb La Sportiva shoes, such as the Muira and the Katana.
Some have described the Boostic as a hybrid, taking the best parts of two previously popular models: the Booster and the Stix. In actual fact this shoe shines on its own merits, by achieving the seemingly impossible: namely, a combination of high performance and comfort.
It is certainly a very neat shoe capable of delivering precision edging and if your feet match the fit (see below) then the claims for unprecedented comfort do ring true.
The toe down, asymmetric shape gives good pulling power on steep ground; the edging performance is also superb, as might be expected of a shoe of this style.
The heel is snug and gives excellent ‘stick’ on marginal heel hooks. The top of the toe box is also covered with a ribbed patch of rubber to help with tricky toe hook manoeuvres.
Rubber: 4mm Vibram® XS Edge
The Boostic has quite a broad fit with a medium volume toe box. The uppers, which are leather at the back and synthetic at the front, are unlined – nonetheless, because of the amount of rubber encasing the shoe, they don’t stretch too much.
We would advise dropping two Euro sizes, or perhaps three Euro sizes from your normal shoe size for a really technical fit.
