The 63" is perfect for the high top Altama OTBs. Perfect to complete your #multicamblackgang loadout.

These laces are great. Threw some 63 inchers on my Reebok Nanos (Men's 14 USA). Perfect length, with enough to easily tie and double-knot without neurosurgical skills. Might be a bit long for smaller sized Nanos; I don't know how much the size affects lace length. I had replaced my original Nano laces with some 60 inchers, but the resulting knot was still a bit short to easily double-up. Besides the good length, the construction is top notch. The material is very thin and light, and I momentarily thought I got scammed with some janky crap with multicam sprinkles on top. However, I placed my trust in Spiritus Systems' penchant for quality, and I wasn't let down. After lacing my shoes and wearing them for a few days, it became apparent the material is not crap. I have yet to put them through the ringer (poky Texas foliage, Father Time, squats, dead lifts, etc.), but so far so good. They don't easily fray, they keep knots well, and what little stretch they have is limited to the fabric's weave structure vs. its fibrous elasticity (I'm guessing these are made of some polyester derivative, and not a nylon), and they stretch uniformly over the normal cross-section of the lace, so I don't expect them to lose lateral strength and snap, or to deform/cup too much. I'm pretty OCD about how small parts affect larger systems, so I enjoy scrutinizing things like shoe laces. These little nope-ropes make me feel farm and fuzzy inside, so I'm happy. I hope my nonsense helps other's find their happy place.

Slapped them on my black low-top vans.

You can definitely use them to tie your shoes.
