Not A Walking Shoe
Size: 9.5, Color: Black/British Tan
In the photo online this shoe looks like it will be very comfortable. Kind of a classy Coach's Shoe. Also in the photo the heel portion of the sole looks thick and supportive. I bought them thinking they would be my go-to travel shoe. Wrong.
This is not a comfortable shoe for extended wear. Short durations, OK. The main problem is that the sole is very thin and flexible in all directions. There is no, as in zero arch support, plus that thin heel means that you tend to rock back on your heels and it feels like you're pounding the pavement.
I've worn once and I'm very disappointed. They look great, definitely high quality materials, but using them for the intended purpose of travel.... fah get about it.
If you're looking for a good looking shoe to wear around the gym and you don't intend to use the treadmill, or elliptical, then this is the shoe you want.
They would definitely be returned if I hadn't already worn them outside.

Waterproof perfect as travel fountain pen case
Awesome very small size waterproof bag. Purchased to use as a travel case for my fountain pens and ink (just in case). Although I have never had an ink accident, I wanted something compact enough to use in a small cross body bag without wasting space for the sake of an extra measure of assurance I wouldn't end up wearing my ink.
NOTE, I do not use the disposable ink cartridges only adapters or dropper fill. So if I were to experience an ink mishap it would be more than just a tiny amount of permanent ink.
The bag seems to be very well made. It is exactly as described, the only thing that may not be obvious is that the material is quite robust and there is no real give. So it works perfectly as a pencase and for a passport or smaller notebook. I would note recommend using it for something thick or round, like an apple or a larger size bottle of ink. However for a syringe full of ink along with half a dozen fountain pens it's superb!
Will definitely buy again when need arises.
This would also make for a great safe case for a smaller phone. However current flagship phones will not fit through the limiting zipper length.
A future improvement of having the zipper go just around the corner to allow full length access would be an awesome improvement which would then be perfect for a newer model cell phone.
