Not sure why SIDI replaced these because they are so good! They fit perfect and true to size. They fee secure and protective especially at the ankle and heel despite being a short boot. They look great! Not too sporty but look and feel the part. And best thing about them is that the ankle cuff is low profile and fits underneath normal pants. Your pant cuff doesn't get stuck over the boot. The boots take about a week to break in and the feel gets better with time. The soles are thin but very stiff so you get a direct connection to the footrests and the road.
