The La Sportiva Raptors are the best shoes I have ever owned. I just ordered my second pair . My search has been for shoes able to double as both great trail running shoes (light weight, grippy turns at speed, fast stoppers, don’t destroy my toes on downhills) as well as great light hikers (carrying a 30 pound pack on long distance desert and mountain backpacking trips). After trying out many specialized trail runners and hiking boots, the Raptors are the first pair to do everything while meeting or exceeding most of my expectations. My average shoe size is 11, but depending upon the manufacturer it can be anything from 11 to 12. My Raptors are 11.5 (45 European).
