Originally, i bought the 262 splits shorts medium, tested, and decided to race the 2025 Boston marathon in them. I had also bought these ribbed ones in small, (per Scully's recommendation of what he wears), tested these the day before Boston marathon race. Wow, i switched over to these. Carried all fuel (no bonk), bounce free, and extremely comfortable. Shipping was quick from UK to USA. A++, Go 262! Great job Scully!
