After being a faithful Asham shoe wearer for over 30 years (from the original grey red brick shoes, to the Slam all leather then the Slam Ultra Lites). Unfortunately the soles (both sides) on my Ultra Lites cracked on the arch. I noticed the Hardline had composite arch supports but used the Asham Rotator Disk System. I have used then during this abbreviated season and so far these live up to all expectations. Light, comfy, warm and great from a performance standard. I highly recommend these shoes.
