Ultramarathon™

The Ultramarathon 48H is the ultimate super long distance running sock available.  Accept no substitutes.  This sock was developed in Europe with a team of ultra long distance runners, and was tested under grueling conditions in 48 hour racing over 300 Km.  Curve Fit System Construction insures that they won’t slip and cause blisters, and the extra padded footbed and toebox, as well as Achilles tendon cushioning makes for outstanding comfort and performance.  We use DuPont Coolmax® Padding and SST Si upper foot material for the ultimate in comfort and moisture management.   Flat toe seams prevent blisters or hot spots.  We’ve spared no expense on this sock, and they are excellent for any serious runner.
