What are the best shoes (spikes? supershoes? xc racing flats? other?) to wear on the cross-country course at the Texas A&M course at College Station, Texas? If spikes, what size spikes (1/4", 3/8", 1/2", 5/8", 3/4", other) would you recommend? Finally, how would your recommendations change if the course is dry compared to wet? [The USATF youth X-C Nationals are being held on this course on Saturday].
