Series 25 Ball Bearing BlockThe Series 25 Ball Bearing Orbit Block is a 1in (25mm) single sheave ball bearing block with becket and lashing head designed to give you high strength and low weight for dinghy and small boat control lines. Its primary benefit is reduced friction under load thanks to a two stage ball bearing system built for control line tasks. Problem: high friction and heavy hardware slow sail handling on small boats. Solution: this block uses a high compression

the size was not what i expected, most shoes i wear have always been a size 8, but this one was a bit tight. I asked a question on the page if the size is based on UK or US since there's a 1 size difference. but it said it was US standard reference. perhaps buying a size 9 would fix this issue for me. The quality of the shoes however is very great, compared to the basic shoe affordable brands you get this one has better quality, they're light and great whether you're stationary or actively jogging or walking. just the size was lacking in fit.

Not comfortable and hurt my ankle. Makes weird leather sounds while walking. Looks good but go for a different shoe if you are looking for comfort.
