Write a Review

November 7, 2012

This is my first pair of riding boots of this kind, so I didn't know what to expect when it came to fit and comfort. I read a few of the other reviews about getting a half size bigger due to the European sizing. Truth is I wish I would have gotten the right size, size 12, instead of 12.5 which fit a little big and a tad loose in the ankle. Also they are a little stiff and walking in them takes a little getting used to....not bad enough for me to return. Overall I'm happy with the purchase.

I would recommend this item to a friend.

Alpinestars S-MX R boots

June 18, 2012

Was looking for a quality boot that wouldn't break the bank. Got these on clearance for a great price. Fit is excellent, although from past euro boot purchases i bought a half size bigger. Extremely happy, and would definitely recommend!

Fantastic Boot

March 23, 2011

The fit was super right out of the box. There are no tight spots, yet the boots fit snug. The opening has ample room to wear jeans or riding leathers under. The fit is exactly like a shoe size which makes finding the right boot easy.

I would recommend this item to a friend.
