Respuesta de SkatePro: Hello Farbod,
Thanks for your comment😊.
It is correct that if you are doing speed skating these wheels can be wider as you would like and not very sharp. So, maybe you should look for models that have narrower and more specific for that discipline 😊.
We recommend brands like matter that are much more specialized in speed skating.
On the other hand, if you need advice, we are at your complete disposal and we will be able to advise you.😁
