First look review: Mavic Cosmic Ultimate SL shoes

15 Jun 2018
Verdict:

Mavic launches a new top-tier lightweight racing shoe, and finally opts into Boa dials

Price: 
£330

The Mavic Cosmic Ultimate SL shoe is the newest in Mavic’s tradition of ultralight climbing shoes, coming in at 199g for a size 42 (EU).

The shoes showcase a host of other new features, most distinctive of which is the inclusion of a set of Boa dials. This is the first time Mavic has diverged from its own closure system, the Mavic Ergo Dial.

Mavic argues that the decision has not been based on function, as Mavic considers its system as effective as Boa, but has based it on consumer demand for the Boa system on a spec sheet.

New design

The shoe has echoes of the infamous Mavic Comete shoe, that used a solid exterior shell, as the upper is built within a TPU frame that is laser welded to ultralight mesh panels to increase stiffness while lowering weight.

The Energy Full Carbon SLR sole is Mavic’s lightest yet, shaving 10g off the previous generation sole but remains fully carbon fibre in construction. It is also extremely thin, making for an ultra low 6.5mm stack height.

Mavic has also expanded the size of the toe-box, widening it to suit common foot shapes, while also tightening the shape of the heel support, which is also integrated into the upper.

A further ergonomic consideration is a low-profile collar to reduce rubbing and constriction when bending and twisting the ankle during hard efforts.

Frank Schleck, Tour de France podium finisher and Mavic brand ambassador, has been central in the design of the Cosmic Ultimate SL, and claimed, ‘In the last 15 years I have never been more happy with a shoe.’

The shoes are also available in a women’s only version, called the Sequence Ultimate SL.
