Features:
Anatomically engineered and profiled specifically for youth and younger riders, the all-new SM3 Youth Helmet is optimized for MX, Enduro and Off-road use, and features a whole raft of technologies and innovations taken from Alpinestars range of adult helmets to deliver the optimal blend of performance, protection and comfort.
- This lightweight helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight.
- Lightweight outer shell is constructed from a technologically advanced impact resistant thermoplastic in three sizes (Youth Small, Youth Medium and Youth Large. The SM3 Youth weighs 1060g (ECE) and 1170g (DOT).
- Separate versions of the shells for DOT and ECE requirements; the DOT certified version of the helmet’s inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts.
- The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as spare parts in different thicknesses.
- Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size, which allows riders with an YM size to initially buy an YM helmet and then configure it to a Youth Large size as they grow via the crown and cheek pad spare parts.
- The Youth Small (YS) has a smaller EPS size and can be customized only via the cheek pads. Alpinestars extensive research has shown that the kids that wear a YS size are very small, typically 3 to 4 years old, and therefore they require a dedicated helmet fit.

Wide toe box, works for fancy or casual
Size: 10 Wide Toddler, Color: White
Perfect fancy wide toe box shoes for toddler. Able to dress down for everyday wear as well. Really good quality, cleans off easily, flexible base, comfortable and easy for my 2 year old to put on and take off herself.

Cute but runs big and made for high volume feet
Size: 8 Wide Toddler, Color: Brown
Cute shoes, otherwise they would only get 3 stars. Do not recommend using the size chart. I used the size chart and tried to measure carefully, yet the first ones we got were literally several sizes too large for my daughter. I returned them and sized down 2 sizes, and they are workable but still on the big side. Beware. They are also extremely high volume. If my daughter wears them barefoot, there is quite a gap between her foot and the top of the sandal. If she wears socks, especially her thick winter socks, it’s closer to a decent fit. Again, beware. I would buy again…not sure. My daughter is very fond of them, and that says a lot. She’s three and has very strong opinions about things😅

Nice quality but a bit big
Size: 8 Wide Toddler, Color: Tan
These seem like great quality. 3 stars because they are large on my child’s wide foot, so I imagine they are even bigger on narrow and/or average feet.
