I’d like to preface this review by saying that rollerskishop.com’s staff were extremely friendly and helpful, helping me select the correct sizing, and this review is in no way reflective on the shop itself, just the product.
Moving onto the boot itself: Put simply, these just aren’t adequate at all for any level of roller skiing. The RSK platform might be usable on snow, where you’re inherently more stable, but on roads they’re practically unusable. They have nothing in the way of torsional rigidity, which is only highlighted when you start to ski harder. They’ve buckled at the worst possible times, causing me to fall where I otherwise probably wouldn’t have. Additionally, the channels on the boots are narrow, so combined with the lack of stiffness in the boot itself, if you don’t land perfectly on the binding, trust that the boot will buckle outwards.
In conclusion, don’t buy these, just spend the money and get ESKs because having stiff boots is so important, especially when rollerskiing. It’s not worth the potential damage to yourself and to the rest of your equipment to cheap out on the boots. Learn from my mistakes.
