These boots are a great entry level summer rollerski boot for skating for use with NNN, Prolink, and Turnamic skate bindings.
Outsole is made out of hard plastic with soft inner to provide good fitting and stability. The reinforced heel comes with a new adjustable system to get more pressure on the heel allowing for adjustable heel fit. Wider fit than Fischer and run a little long for the euro sizing. We would be happy to measure the insoles of these for you to compare to some of yours to help ensure proper fit on first try.
