I bought these laces for my Ultra Boost ST. Despite there is no assurance that it will fit, I am happy to say that it fits perfectly well!
Was looking for a new site for laces and found Lace Lab. Had a few questions which were answered immediately and knowledgeably. Ordered 4 pairs and received quickly! Happy to use again and again!
