These days, many kids are absolutely crushing. Now, if that 7 or 8-year-old starts climbing harder than mom or dad, they too, can get an aggressive, performance-driven shoe, just like the adults with the La Sportiva Maverink. The P3 platform gives it a nice downturn for bouldering or steep sport climbing, but the tension in the rand is not pulled quite as tight as the adult performance shoes, and the whole forefoot from the arch to the toes, is almost flat. So, while it may be "super aggressive" when compared to the Evolv Venga, it remains forgiving to the young growing foot and won't hold the foot in an unnaturally tight slingshot position.
It's an unlined, slip lasted shoe with a soft microfiber upper, and a nice leather heel pocket, surrounded by rubber, that is great for heel hooking. The Maverink has La Sportiva's proprietary No-Edge technology that gets the toe closer to the rock, letting you use your climbing shoes almost like a second skin, and the XS Grip 2 rubber has excellent friction for sticking to small holds. Much of the forefoot was left free of seams and overlays because the Maverink comes with two markers so they can be fully personalized to match the style of the climber.
Kids just moving up from a more all around, flat lasted shoe will find pulling these slippers on to be more difficult than something with a wide, hook and loop strap. The rigid P3 rand also wraps around the back of heel a bit higher than most other shoes and can create a pressure point on the back of the ankle. Some of that is just the side effect of having the added performance of the P3 rand and a nice deep heel pocket. But overall, for what this shoe is and does, it is incredibly comfortable.
