Black Diamond Momentum Kids
Black Diamond
The Momentum Kids is a medium-soft, flat-lasted velcro kids' shoe from Black Diamond for sport climbing and bouldering. Black Diamond lists it as medium-width with a medium heel. In stock at 9 shops from 45.29 EUR.
The kids' version of Black Diamond's Momentum: a classic flat last, a micro suede upper with a knit tongue for breathability, an easy hook-and-loop closure and a round, soft toe box that accommodates a foot still changing shape. Black Label rubber is the durable end of BD's range, which is the right trade for a shoe that lives in a gym. Black Diamond sells it in two size blocks, EU 29-35 for ages 6-7 and EU 33-38 for ages 7-12.
Best For
Best for sport climbing and bouldering on slab and vertical terrain. Aimed at beginner climbers.
Measured against the 469 adult climbing shoes we track, the Momentum Kids would rank in the top 14% for comfort, the top 39% for sensitivity and the top 48% for crack climbing.
Strengths & Trade-offs
Momentum Kids strengths
- Flat, neutral shape stays comfortable through a whole gym session
- Round, soft toe box leaves room for a foot that is still changing shape
- Single hook-and-loop strap for quick, easy entry
- Black Label rubber is Black Diamond's durability compound, made for gym wear
- Two size blocks, EU 29-35 and EU 33-38, cover roughly ages 6 to 12
Momentum Kids trade-offs
- Flat shape gives no help on steep or overhanging walls
- Partial heel rubber limits heel hooks
- Synthetic upper barely stretches, so break-in adds little room as a child's foot grows
How the Momentum Kids fits
Fit for comfort, not performance. BD's own guidance for the Momentum family is roughly half to one EU size below street size for all-day comfort; with a growing foot, err towards the comfortable end.
Fit profile: medium width, standard forefoot volume, medium heel, suits egyptian and roman toe shapes.
Minimal stretch expected; minimal break-in.
